Molluscum contagiosum
Leczenie

Molluscum contagiosum to samoograniczające się zakażenie wirusowe skóry, które u osób z prawidłową odpornością ustępuje zwykle w ciągu 6-18 miesięcy, choć całkowite wyleczenie może trwać do 2-5 lat. Leczenie jest wskazane w przypadku zmian w okolicach narządów płciowych, rozległych lub widocznych zmian, dyskomfortu, obniżonej odporności (np. HIV/AIDS) oraz współistniejących chorób dermatologicznych. Do 2023 roku nie było zatwierdzonych przez FDA leków specyficznych dla tej choroby, jednak kantarydyna (Ycanth 0,7% roztwór) została zatwierdzona jako pierwszy preparat, aplikowany co 3 tygodnie, wykazując 54% skuteczność całkowitego ustąpienia zmian do 84. dnia. Nowością jest również berdazimer, lek uwalniający tlenek azotu, zatwierdzony w 2024 roku, z 32% skutecznością w badaniach klinicznych. Metody destrukcyjne, takie jak krioterapia, łyżeczkowanie, laseroterapia i elektrokoagulacja, pozostają powszechnie stosowane, choć wiążą się z ryzykiem bólu, podrażnień i bliznowacenia.

Leczenie Molluscum contagiosum

Molluscum contagiosum to zakażenie wirusowe skóry, które zazwyczaj ustępuje samoistnie w ciągu 6-18 miesięcy bez konieczności leczenia u osób z prawidłowo funkcjonującym układem immunologicznym12. Indywidualne zmiany rzadko utrzymują się dłużej niż 2 miesiące, choć całkowite ustąpienie wszystkich zmian może trwać nawet do 2-5 lat34. Pomimo samoograniczającego się charakteru infekcji, istnieją sytuacje, w których wskazane jest wdrożenie leczenia.

Wskazania do leczenia

Leczenie Molluscum contagiosum może być zalecane w następujących przypadkach56:

  • Zmiany w okolicach narządów płciowych – w celu zapobiegania transmisji seksualnej
  • Rozległe zmiany lub te umiejscowione w widocznych miejscach (względy kosmetyczne)
  • Zmiany powodujące dyskomfort, ból lub świąd
  • Pacjenci z obniżoną odpornością (np. z HIV/AIDS)
  • Współistniejące choroby dermatologiczne (np. atopowe zapalenie skóry)
  • Zapobieganie autoinokulacji (samozakażeniu)
  • Zmniejszenie ryzyka przeniesienia wirusa na osoby z bliskiego kontaktu

Opcje terapeutyczne

Wybór metody leczenia zależy od wielu czynników, takich jak: wiek pacjenta, liczba i lokalizacja zmian, współistniejące choroby, preferencje pacjenta oraz doświadczenie lekarza37. Należy zauważyć, że do 2023 roku nie istniał żaden preparat zatwierdzony przez FDA specyficznie do leczenia Molluscum contagiosum, jednak sytuacja ta uległa zmianie wraz z zatwierdzeniem kantarydyny8.

Metody fizycznego usuwania zmian

Metody destrukcyjne są najczęściej stosowanymi procedurami w praktyce klinicznej i prowadzą do zniszczenia keratynocytów zainfekowanych wirusem7. Obejmują one:

  • Krioterapia – zamrażanie zmian ciekłym azotem. Jest to skuteczna metoda, choć może być bolesna i nie jest zalecana u małych dzieci59. Może pozostawiać białe ślady na skórze10.
  • Łyżeczkowanie (curettage) – procedura polegająca na mechanicznym usunięciu zmian przy użyciu specjalnego narzędzia zwanego łyżeczką. Metoda jest skuteczna, ale może powodować dyskomfort i pozostawiać blizny47.
  • Laseroterapia – wykorzystanie lasera CO2 lub lasera pulsacyjnego do usuwania zmian. Jest to opcja dla pacjentów z wieloma zmianami lub trudnymi do leczenia przypadkami, np. u osób z AIDS1112.
  • Elektrokoagulacja – metoda wykorzystująca prąd elektryczny do usuwania zmian10.

Metody fizyczne wymagają zazwyczaj znieczulenia miejscowego, mogą powodować ból po zabiegu, podrażnienie i bliznowacenie9.

Leki miejscowe

Istnieje szereg preparatów do stosowania miejscowego w leczeniu Molluscum contagiosum94:

  • Kantarydyna (Ycanth) – pierwszy preparat zatwierdzony przez FDA do leczenia Molluscum contagiosum u pacjentów w wieku 2 lat i starszych. Jest aplikowany przez lekarza na zmiany skórne co 3 tygodnie według potrzeb8. Podczas badań klinicznych 54% pacjentów leczonych kantarydyną osiągnęło całkowite ustąpienie wszystkich zmian do 84. dnia w porównaniu z 13% w grupie placebo8. Kantarydyna powoduje powstanie pęcherza, który odrywa zmianę od skóry – pacjent powinien zmyć lek wodą z mydłem w czasie określonym przez lekarza5.
  • Berdazimer – nowy lek miejscowy uwalniający tlenek azotu, który został zatwierdzony na początku 2024 roku4. W badaniach klinicznych wykazywał całkowite ustąpienie zmian u 32% pacjentów13.
  • Podofilotoksyna (0,5% krem) – niezalecana dla kobiet w ciąży ze względu na potencjalną toksyczność dla płodu9.
  • Imikwimod – modyfikator odpowiedzi immunologicznej. Dostępny dla dorosłych, nie wykazano skuteczności u dzieci9.
  • Wodorotlenek potasu – substancja powodująca rozpad komórek skóry zainfekowanych wirusem14.
  • Kwas salicylowy – substancja keratolityczna dostępna w stężeniach 10-30%7.
  • Nadtlenek benzoilu – dostępny w postaci kremu lub żelu14.
  • Tretynoina – pochodna witaminy A stosowana miejscowo 1-2 razy dziennie na pojedyncze zmiany14.
  • Kwas trójchlorooctowy – powoduje niszczenie tkanek poprzez koagulację i powierzchowną martwicę7.
  • Azotan srebra – wywołuje reakcję miejscową7.

Niektóre z tych preparatów mogą powodować miejscowe podrażnienie, zaczerwienienie, pieczenie lub świąd15.

Leczenie ogólnoustrojowe

W niektórych przypadkach stosowane są również leki doustne916:

  • Cymetydynaantagonista receptorów H2, stosowany zwłaszcza u dzieci jako alternatywa dla boleśniejszych metod. Jest bezpieczny i dobrze tolerowany, choć zmiany na twarzy gorzej reagują na leczenie9.
  • Cidofowir – inhibitor polimerazy DNA, stosowany z powodzeniem u osób z obniżoną odpornością, jednak może powodować nefrotoksyczność i neutropenię przy podawaniu dożylnym3.
  • Terapia antyretrowirusowa (ART) – u osób z HIV/AIDS najskuteczniejszym podejściem jest wdrożenie wysoce aktywnej terapii antyretrowirusowej (HAART), która wzmacnia układ odpornościowy i pomaga w walce z wirusem317.

Leczenie pacjentów z obniżoną odpornością

Pacjenci z obniżoną odpornością (np. z HIV/AIDS) stanowią szczególne wyzwanie terapeutyczne49:

  • Zmiany mogą być rozległe, duże i trudne do leczenia
  • Tradycyjne metody leczenia często są nieskuteczne
  • Najlepsze efekty przynosi wzmocnienie układu odpornościowego
  • W skrajnych przypadkach stosuje się doogniskowe podanie interferonu, choć może ono powodować nieprzyjemne działania niepożądane (objawy grypopodobne, bolesność, depresja)
  • Terapia antyretrowirusowa jest kluczowa dla pacjentów z HIV

Nowoczesne podejście do leczenia

W ostatnich latach nastąpił przełom w leczeniu Molluscum contagiosum dzięki zatwierdzeniu przez FDA pierwszego oficjalnego leku – kantarydyny (Ycanth) oraz badaniom nad nowymi preparatami813.

Kantarydyna (Ycanth)

Kantarydyna w postaci preparatu Ycanth (0,7% roztwór) jest pierwszym lekiem zatwierdzonym przez FDA do leczenia Molluscum contagiosum8. Lek ten jest aplikowany przez lekarza na zmiany skórne co 3 tygodnie według potrzeb. Kantarydyna działa jako środek pęcherzący, powodując powstanie pęcherza wodnego, który odrywa zmianę od skóry18. Pacjent powinien zmyć lek wodą z mydłem w czasie określonym przez lekarza (zwykle po 2-6 godzinach)19.

W badaniach klinicznych wykazano, że 54% pacjentów leczonych kantarydyną osiągnęło całkowite ustąpienie wszystkich zmian do 84. dnia, w porównaniu z 13% w grupie placebo8. Lek jest przeznaczony dla pacjentów w wieku 2 lat i starszych8.

Berdazimer

Berdazimer to nowy lek miejscowy uwalniający tlenek azotu (NO), który został zatwierdzony na początku 2024 roku4. Składa się z żelu zawierającego sól sodową berdazimeru i hydrożel karboksymetylocelulozy, który działa jako donor protonów13.

W badaniach klinicznych fazy III berdazimer wykazywał całkowite ustąpienie zmian u 32% pacjentów, z łagodnymi do umiarkowanych miejscowymi reakcjami skórnymi13. Lek może być stosowany u pacjentów od 1. roku życia16.

Leczenie współistniejących problemów skóry

W przypadku wystąpienia wtórnych problemów skórnych związanych z Molluscum contagiosum, mogą być stosowane dodatkowe metody leczenia1020:

  • Zapalenie skóry wokół zmianmiejscowe kortykosteroidy o odpowiedniej mocy i formulacji (np. hydrokortyzon) mogą łagodzić świąd, suchość lub bolesność skóry
  • Wtórne zakażenie bakteryjne – może wymagać zastosowania antybiotyków
  • Reakcja zapalna – łagodne leki przeciwzapalne

Leczenie współistniejących chorób skóry (np. atopowego zapalenia skóry) przed przystąpieniem do leczenia Molluscum contagiosum może poprawić wyniki terapii21.

Leczenie u dzieci

Leczenie Molluscum contagiosum u dzieci wymaga szczególnej uwagi, ponieważ wiele metod może być bolesnych lub powodować dyskomfort22:

  • U większości dzieci zmiany ustępują samoistnie bez leczenia
  • Niektórzy lekarze nie zalecają agresywnego leczenia u dzieci ze względu na możliwość wywołania bólu, pęcherzy, przebarwień lub blizn
  • Cymetydyna doustna jest często preferowana dla dzieci, ponieważ jest bezbolesna, bezpieczna i dobrze tolerowana
  • Kantarydyna (Ycanth) jest stosunkowo dobrze tolerowana przez dzieci, ponieważ aplikacja nie jest bolesna
  • W przypadku leczenia dzieci należy omówić z lekarzem sposoby zapobiegania bólowi, bliznowaceniu i zmianom pigmentacji skóry po leczeniu

Podejście do leczenia – ogólne zasady

Podejmując decyzję o leczeniu Molluscum contagiosum, należy wziąć pod uwagę następujące czynniki1818:

  • Samoistne ustąpienie zmian może trwać od kilku miesięcy do kilku lat
  • Leczenie może przyspieszyć ustąpienie zmian i zapobiec rozprzestrzenianiu się wirusa
  • Wybór metody leczenia powinien być dostosowany do wieku pacjenta, lokalizacji i liczby zmian oraz ogólnego stanu zdrowia
  • Leczenie może wymagać wielokrotnych wizyt i procedur
  • Należy rozważyć potencjalne działania niepożądane poszczególnych metod leczenia
  • Ważne jest, aby nie stosować nieprzetestowanych preparatów dostępnych w internecie, które mogą być nieskuteczne lub wręcz szkodliwe

Przed rozpoczęciem jakiejkolwiek terapii wskazana jest konsultacja z dermatologiem lub innym specjalistą, który może zaproponować najbardziej odpowiednie leczenie dla konkretnego przypadku15.

Podsumowanie i konsekwencje dla praktyki klinicznej

Molluscum contagiosum jest zwykle łagodnym, samoograniczającym się zakażeniem, które w większości przypadków nie wymaga leczenia1. Jednakże w określonych sytuacjach klinicznych leczenie może być wskazane, aby zapobiec rozprzestrzenianiu się wirusa, zmniejszyć dyskomfort lub ze względów kosmetycznych18.

Zatwierdzenie przez FDA kantarydyny (Ycanth) jako pierwszego oficjalnego leku do leczenia Molluscum contagiosum oraz pojawienie się nowych opcji terapeutycznych, takich jak berdazimer, stanowi istotny postęp w leczeniu tej choroby84. Niemniej jednak, wybór metody leczenia powinien być zawsze zindywidualizowany i uwzględniać korzyści oraz potencjalne ryzyko dla każdego pacjenta7.

Dla lekarzy praktyków ważne jest, aby być na bieżąco z najnowszymi opcjami terapeutycznymi i zaleceniami dotyczącymi leczenia Molluscum contagiosum, szczególnie w kontekście zatwierdzonych przez FDA preparatów, które oferują standaryzowane, bezpieczne i skuteczne podejście do leczenia tego częstego zakażenia skóry18.

    https://www.mayoclinic.org/diseases-conditions/molluscum-contagiosum/diagnosis-treatment/drc-20375230
    Molluscum contagiosum usually gets better without treatment in 6 months to 2 years. Once the bumps are gone, you’re no longer contagious. After healing, it’s possible to become reinfected with the virus. […] For severe or widespread disease, your health care provider might refer you to a specialist in skin conditions (dermatologist) to discuss options for removing the bumps. […] Treatment might involve one or a combination of the following: A medicine that irritates the sores, such as retinoic acid or benzoyl peroxide, A medicine that causes blisters (cantharidin), which lifts off the bumps, Scraping, Freezing (cryotherapy), Laser therapy, which might be an option for people with a weakened immune system. […] Some procedures can be painful, so your health care provider may numb your skin first. Possible side effects of treatment are infection and scarring.

    Treatment for molluscum contagiosum isnt necessary, as the infection can clear up on its own. […] For children, people with a weakened immune system or people who have symptoms that cause pain and discomfort, treatment could include: […] Removing the papules: Your provider could use different therapies to remove visible signs of the condition from your skin by freezing the papule (cryotherapy), scraping out the papule (curettage) or using a laser to remove it (laser therapy). […] Taking medicine: Medicine is common to treat infections in kids like cimetidine (oral). […] Using topical creams or ointments: Topical creams and ointments speed up your recovery time and reduce symptoms. Topical medicine could include podophyllum, potassium hydroxide, salicylic acid, benzoyl peroxide and tretinoin. […] Removal of the papules could cause scarring. […] Treatment can reduce your symptoms, especially pain and itching, and can speed up your healing time.

    People frequently seek treatment for cosmetic reasons, to avoid social stigma, or because they have concerns of transmission to other individuals. […] The treatment depends on the patients (or their parent’s) preferences. Because the condition is usually self-limiting, awaiting spontaneous resolution should be considered. However, the patients should be aware that the resolution of molluscum contagiosum may take several months. Even though many treatments had been proposed for molluscum contagiosum, none has proven its effectiveness. Current treatment options include physical removal of mollusca, topical medications, and systemic treatment. […] Physical removal is based mainly on cryotherapy with liquid nitrogen or curettage. Techniques might be associated. Laser treatment (carbon dioxide or pulsed dye laser) may also be used but not as first-line therapy. Physical removal is usually painful and may require local anesthesia. Postoperative scarring is possible. Topical trichloroacetic acid can be used to treat mollusca with minimal scarring.

    Doctors recommend many topical treatments for molluscum contagiosum. Podophyllotoxin (contraindicated in pregnant women), potassium hydroxide, salicylic acid (associated or not with povidone-iodine), benzoyl peroxide, and tretinoin are used as home treatments and must be applied to each lesion. They are used with the aim to induce an inflammatory reaction, thus accelerating recovery. In a recent analysis, imiquimod, which is used as a modulator of the immune system, and cantharidin, a blistering topical applied by the physician, has not been found to be more effective than other vehicles. […] The use of oral cimetidine has been described as a safe alternative to physical removal in children who fear pain (except for facial involvement). However, a recent meta-analysis did not show any difference with cimetidine. Cidofovir, a DNA polymerase inhibitor, has been used successfully in immunosuppressed persons, but it may induce nephrotoxicity and neutropenia when used intravenously. In people living with HIV/AIDS, molluscum contagiosum is best managed with highly active antiretroviral therapy (HAART).

    https://emedicine.medscape.com/article/910570-treatment
    In healthy patients, molluscum contagiosum is generally self-limited and heals spontaneously after several months. Individual lesions are seldom present for more than 2 months. Although treatment is not required, it may help to reduce autoinoculation or transmission to close contacts and improve clinical appearance. […] Intervention may also be indicated if lesions persist. Therapeutic modalities include topical application of various medications, radiation therapy, and/or surgery. Each technique may result in scarring or postinflammatory pigmentary changes. Frequently, multiple treatment sessions are necessary because of the recurrence of treated lesions and/or the appearance of new lesions. […] Therapeutic options for molluscum contagiosum can be divided into broad categories, including the following: Benign neglect, Direct lesional trauma, Antiviral therapy, Immune response stimulation.

    https://emedicine.medscape.com/article/910570-treatment
    In a study of the treatment of molluscum contagiosum in children, Hanna et al determined that curettage was the most efficacious therapy. […] Curettage was found to be the most efficacious treatment and had the lowest rate of adverse effects. […] Repeat examination is recommended 2-4 weeks after treatment. Retreatment often is necessary. Consider combination therapy in patients whose lesions respond poorly. […] Clinical success has been reported with the use of the following topical agents, which may act as irritants, stimulating an immunologic response: Cantharidin topical, Berdazimer topical, Tretinoin, Bichloracetic acid, Trichloroacetic acid, Salicylic acid, Lactic acid, Glycolic acid, Silver nitrate, Potassium hydroxide, Dilute povidone iodine. […] Cantharidin is a chemovesicant that is highly effective in treating molluscum contagiosum; however, this agent has lost favor with some physicians because of concerns regarding its safety.
  • #4 Molluscum Contagiosum Treatment & Management: Approach Considerations, Pharmacologic Therapy, Benign Neglect
    https://emedicine.medscape.com/article/910570-treatment
    The most appropriate therapeutic approach largely depends on the clinical situation. In healthy children, a major goal is to limit discomfort, and benign neglect or minor, direct lesional trauma is appropriate. In adults who are more motivated to have their lesions treated, cryotherapy or curettage of individual lesions is effective and well tolerated. […] In immunocompromised individuals, molluscum contagiosum may be very extensive and difficult to treat. The goal may be to treat the most troublesome lesions only. In severe cases, these patients may warrant more aggressive therapy with lasers, antiviral therapy, or a combination of these. […] In 2023, the US Food and Drug Administration (FDA) approved the first topical agent, cantharidin, for treatment of molluscum contagiosum. Another topical agent, berdazimer, was approved in early 2024.

    If you have molluscum, your dermatologist may recommend letting this condition clear on its own rather than treating it. […] Treatment may be recommended for patients who have: […] If you have an HIV infection and molluscum, the bumps can be big and cover a large area of skin. Starting antiretroviral therapy (ART) can help clear your skin of molluscum. […] To avoid products that dont work and to prevent possible side effects, use a non-prescription product only when recommended by your dermatologist. […] If treatment is recommended, your dermatologist may recommend treatment that you: […] The goal of an in-office treatment is to destroy the bumps without harming the skin. […] When your dermatologist uses cantharidin (beetle juice) to treat molluscum, you need to wash it off at home with soap and water, within the time frame that your dermatologist gives you.
  • #5 Molluscum contagiosum: Diagnosis and treatment
    https://www.aad.org/public/diseases/a-z/molluscum-contagiosum-treatment
    When applied by a dermatologist, cantharidin is a safe and effective treatment for molluscum. […] Cryosurgery can be painful, so its not always recommended for young children. […] During this treatment, your dermatologist uses a medical device called a curette to remove the molluscum bumps from the skin. […] This may be a treatment option for someone who has many molluscum bumps. […] Sometimes, molluscum is best treated with a medication that you apply at home. […] This prescription medication works to clear or reduce the bumps. […] This prescription medication helps stimulate the bodys immune system so that it will clear the bumps. […] While this is a non-prescription treatment, you should only use it if your dermatologist recommends it. […] For most people, the skin will clear without treatment, usually within 18 months. […] Treating molluscum may clear the skin more quickly; however, the bumps can return after treatment.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC10453394/
    Molluscum contagiosum (MC) is a viral infection that affects primarily pediatric patients, sexually active young adults, and immunocompromised people of all ages. […] Many treatments exist, but only onea drug-device product using topical cantharidin is approved by the United States (US) Food and Drug Administration (FDA) for treatment of MC. […] Unfortunately, this noninterventional approach can increase risk of spreading infection and result in longer duration of infection, physical discomfort, and psychosocial issues due to persistence of the MC lesions. […] The recently updated Red Book Atlas of Pediatric Infectious Diseases states that therapy for MC may be warranted to alleviate discomfort, including itching; reduce autoinoculation; limit transmission of the virus to close contacts and reduce cosmetic concerns and prevent secondary infections.

    https://www.actasdermo.org/es-update-on-treatment-molluscum-contagiosum-articulo-S1578219018301379
    Because MC is benign and self-limiting, a wait-and-see approach is reasonable. […] The choice of treatment depends on the number of lesions, their location, potential adverse effects, parental preferences, and the physician’s experience. […] In principle, MC should be treated using modalities that cause minimal pain and scarring.

    Molluscum contagiosum is one of the most common viral infections in childhood. It is a benign and usually self-limiting infection, but its treatment in children can be challenging, particularly when the patient presents multiple lesions or when lesions are symptomatic or highly visible. Several treatment options exist. Choice of treatment depends on the number and location of lesions, the prior experience of the treating physician, and the preferences of the child’s parents or carers. This article provides an update on treatment options for molluscum contagiosum, with a particular focus on immunocompetent pediatric patients. […] Treatment options for MC lesions are listed in Table 1. Those that have been used in pediatric patients are described below. […] Destructive methods are the most commonly used methods in routine practice and result in the destruction of keratinocytes infected by the MC virus. These simple and inexpensive procedures, when carried out by a suitably qualified health care professional, are very effective.

    https://www.actasdermo.org/es-update-on-treatment-molluscum-contagiosum-articulo-S1578219018301379
    Curettage is a simple and relatively inexpensive procedure, with the added advantage that the tissue removed can be kept for histopathological analysis in case of diagnostic doubt. […] Curettage is probably one of the most effective methods. […] The umbilicated nucleus of the lesion can be manually removed using the hands or any one of a variety of instruments, including a scalpel, lancet, insulin needle, slide, or forceps. […] Trichloroacetic acid causes tissue destruction by immediate chemical coagulation and superficial necrosis. […] Salicylic acid is a keratolytic agent sold at concentrations of 10% to 30%. […] Hydrogen peroxide (HP) is a powerful oxidizing agent and antiseptic that can inactivate poxvirus in vitro. […] Cantharidin is a vesicant agent produced by the beetle Lytta vesicatoria.

    Potassium hydroxide (KOH) is an alkali that penetrates and destroys the skin by dissolving keratin. […] The application of liquid nitrogen at 196C induces the formation of intracellular and extracellular ice crystals, which cause tissue destruction and changes in the cell membrane and circulation in the skin. […] Immunotherapeutic methods are based on the stimulation of a cellular and/or humoral immune response that can eliminate the viral infection. […] Oral cimetidine is an antagonist of H2 histamine receptors. […] Candidin, a substance derived from the purified extract of Candida albicans, is usually used to treat warts but has been proposed as a treatment option for MC. […] Silver nitrate is prepared with 0.2mL of a 40% aqueous solution of silver nitrate and 0.05g of flour. […] The evidence base supporting several treatments of scarce efficacy is weak, but they are harmless and generally well accepted by parents and caregivers.

    https://www.fda.gov/drugs/news-events-human-drugs/fda-approves-first-treatment-molluscum-contagiosum
    FDA has approved Ycanth (cantharidin) for the topical (used on the skin) treatment of molluscum contagiosum in adult and pediatric patients 2 years of age and older. Ycanth is the first FDA-approved treatment for molluscum. Ycanth is administered to patients only by health care providers. Providers apply a single application of Ycanth on the areas of patients skin with molluscum bumps every 3 weeks as needed. […] The efficacy of Ycanth for the treatment of molluscum in patients 2 years and older was established in two double-blind, randomized, placebo-controlled trials (Trial 1 [NCT03377790] and Trial 2 [NCT03377803]). […] Fifty-four percent of subjects treated with Ycanth achieved complete clearance of all treated molluscum bumps by day 84 compared to 13% of subjects treated with placebo.

    The lesions caused by molluscum are usually benign and resolve without scarring if left alone. Trying to remove lesions by scraping and scooping increases the risk of scarring and is not recommended for otherwise healthy people. […] Physical removal such as cryotherapy, curettage and laser therapy require a trained healthcare provider and often local anesthesia. These procedures can result in post-procedural pain, irritation, and scarring. […] Gradual removal of lesions may be achieved by oral therapy with cimetidine. This option is often preferred for pediatric patients because: It is less painful. Parents can administer it at home. It has less chance of leaving scars. […] While cimetidine is safe, painless, and well tolerated, facial mollusca do not respond as well as lesions elsewhere on the body. In patients with facial mollusca, consider other treatment options, such as topical therapy.

    There are a number of topical treatments that are available for molluscum infections. These treatments must be prescribed by a healthcare professional. […] Podophyllotoxin cream (0.5%) is a reliable home therapy for women who are not pregnant. Each lesion must be treated individually as the therapeutic effect is localized. It is not recommended during pregnancy due to the potential risk to the fetus. […] Other options for topical therapy include iodine and salicylic acid, potassium hydroxide and tretinoin. Another therapy, the blistering agent cantharidin, is available but must be applied in a healthcare provider’s office. […] Imiquimod (a T-cell modifier) is available for adults. It has not been proven effective in children and is not recommended for children due to possible adverse events.

    Thus far, the most effective therapy for immunocompromised people who have molluscum are those that boost their immune systems. […] In extreme cases, intralesional interferon has been used to treat facial lesions in these patients. However, interferon can cause severe and unpleasant side effects (flu-like symptoms, site tenderness, depression, and lethargy). These side effects make interferon a less desirable treatment. […] Radiation therapy is also of little benefit.

    There is no single perfect treatment of molluscum contagiosum since we are currently unable to kill the virus. In many cases no specific treatment is necessary. […] Physical treatments include picking out the soft white core (note, this could lead to autoinoculation), cryotherapy (can leave white marks), gentle curettage or electrodessication (can scar), and laser ablation (can scar). […] Medical treatments include antiseptics such as hydrogen peroxide cream or povidone iodine solution, podophyllotoxin cream, wart paints containing salicylic acid, cantharidine solution, and under review: berdazimer gel is under FDA review with anticipated approval in early 2024. […] Secondary dermatitis may be treated symptomatically with a mild topical topical corticosteroid such as hydrocortisone cream. Dermatitis is unlikely to fully resolve until the molluscum infection has cleared up.

    As molluscum contagiosum is caused by a virus, the condition will persist until the immune system clears the virus. […] Your dermatologist will provide a customized treatment plan to help clear your childs molluscum infection as quickly as possible. […] There are many treatment options available for molluscum. Topical creams (imiquimod, tretinoin) might be used alone or in conjunction with other procedures aimed at eliminating the lesions. […] Procedures performed in dermatologist offices to remove molluscum lesions include cryotherapy (light freezing), curettage (scraping), and cantharidin (beetlejuice!) application.

    Prevention includes hand washing and not sharing personal items. […] While treatment is not necessary, some may wish to have the lesions removed for cosmetic reasons or to prevent spread. Removal may occur with freezing, laser therapy, or opening up the lesion and scraping the inside. […] The oral medication cimetidine, or podophyllotoxin cream applied to the skin, may also be used for treatment. […] Studies have found cantharidin to be an effective and safe treatment for removing molluscum contagiosum. […] Surgical treatments include cryosurgery, in which liquid nitrogen is used to freeze and destroy lesions, as well as scraping them off with a curette. […] A 2014 systematic review of case reports and case series concluded that the limited available data suggest pulsed dye laser therapy is a safe and effective treatment for molluscum contagiosum and is generally well tolerated by children. […] Berdazimer sodium is a medication used for the treatment for molluscum contagiosum. […] Imiquimod is a form of immunotherapy initially proposed as a treatment for molluscum based on promising results in small case series and clinical trials.

    Do not purchase or use nonprescription (over-the-counter, or OTC) products that claim to treat molluscum, even if the companies make statements that suggest their product may have been reviewed or is endorsed by the FDA. […] Its likely that unapproved products marketed to treat molluscum do not do what they claim, and the ingredients in them could cause adverse effects (bad reactions). The FDA has received reports of side effects in children and adults associated with some of these products, including skin reddening, abrasion from skin scratching, and permanent scarring. […] Many unapproved products claiming to treat molluscum contain essential oils. Even natural substances, such as essential oils, may cause an allergic reaction or irritate sensitive skin.

    While the benign neglect approach to treating MC might appeal to patients with MC, especially the parents/caretakers of children with MC, what is often lost in its explanation is that MC can potentially persist for several months to years in many individuals, can be spread to others who are in close personal contact with the patient, and can lead to real world psychosocial issues in the patient (e.g., feelings of embarrassment and/or fear of transmitting the virus to others, anxiety, social isolation). […] Additionally, the pain and pruritus associated with MC can also negatively impact a pediatric patients quality of life, which further underscores the importance of taking an active approach to treatment of MC and should be factored in the clinician-patient/parent decision-making process.

    Although molluscum eventually resolve, lesions spread easily, may become infected, may be itchy or irritated and are sometimes cosmetically objectionable. Therefore, they are often removed. The treatment depends on the age of the patient and the size and location of the growths. […] Cantharone, a blistering agent made from beetles, is applied with a wooden applicator to the skin growth. The medicine should be washed off in 4 to 6 hours. A small blister usually forms in a few hours to one day. When the scab falls off, the growth is gone. This treatment is useful because the application is not painful; it is used carefully and selectively on the face and in skin creases. Occasionally no blistering occurs, but sometimes, children are quite sensitive and extensive blistering is seen. Scarring does not occur from Cantharone treatment. Although the blisters are uncomfortable, they are very superficial and resolve within a few days. Compresses with lukewarm water and breaking the blisters with a sterile needle may help.

    Most of the time, molluscum clears up on its own without treatment. Each bump goes away in about 2-3 months. New bumps can appear as old ones go away, so it can take 6-12 months (and sometimes longer) for molluscum to fully go away. […] Sometimes, doctors remove the bumps or help them go away more quickly. To do this, they can: Freeze the bumps off. Scrape or cut the bumps off. Put a chemical on the bumps to make the body fight them away faster. Put medicine on the bumps or give medicine to swallow. […] Many doctors don’t recommend these treatments for kids, though. That’s because they can be painful and burn, blister, stain, or scar the skin. When deciding to treat a rash, they consider where the bumps are and if they’re causing itching, pain, or other problems. […] Talk with your child’s doctor about the pros and cons of treating molluscum. The rash usually doesn’t cause long-term problems or leave scars. Often, the best way to handle it is to be patient, as hard as that might be.
