  Polymorphous light eruption is a rash caused by sun exposure in people who are sensitive to sunlight. […] Symptoms of the rash in polymorphous light eruption may include: Dense clusters of small bumps and blisters. Inflamed, raised rough patches. Itching or burning. […] The rash that results from polymorphous light eruption can look different from person to person but typically includes inflammation, itching and small bumps that may be densely packed together. […] In polymorphous light eruption, eruption refers to the rash, which usually appears 30 minutes to several hours after sun exposure. The rash usually appears on areas of the body that are covered during winter but exposed in summer such as the upper chest, front of the neck and arms. […] Polymorphous light eruption usually goes away on its own without scarring within 10 days. People with severe or persistent rashes may need medicine. […] People may rarely have other symptoms such as fever and chills.

  https://ufhealth.org/conditions-and-treatments/polymorphous-light-eruption

  Polymorphous means taking on different forms, and eruption means rash. As the name suggests, symptoms of PMLE are rash-like and are different in different people. […] PMLE most often occurs in spring and early summer on areas of the body exposed to the sun. […] Symptoms usually appear within 1 to 4 days after exposure to sunlight. They include any of the following: Small bumps (papules) or blisters, Redness or scaling of the skin, Itching or burning of the affected skin, Swelling, or even blisters (not often seen). […] It usually appears 1 to 2 days following exposure to sunlight and may last up to one week. It appears as recurrent redness (erythematous) and/or blistered patches (plaques).

• #3 Polymorphic light eruption (PLE) – British Skin Foundation

  https://knowyourskin.britishskinfoundation.org.uk/condition/polymorphic-light-eruption/

  The rash (pink or red spots) of PLE can itch or have a burning sensation. […] PLE ranges from a mild rash that lasts for only a short time to a severe and extensive eruption affecting the quality of life. […] The rash usually disappears by itself within 7-10 days, if there is no further exposure. It heals without scaring. […] Most people with PLE get a rash in the spring after they become exposed to strong sunlight for the first time of the year or when visiting countries with a sunny climate, and sometimes it clears up before they return home. The rash tends to affect areas that have been covered by clothing during the winter and goes away without treatment in about a week if there is no further sun exposure. If the affected area is exposed to more sun the rash will get worse and spread; but as the summer continues, the skin becomes resistant to sunlight and many people can stay longer in the sun.

• #4 Polymorphous Light Eruption– An Indian Scenario

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8088173/

  Polymorphous light eruption (PMLE) is the most common, idiopathic, acquired photodermatosis, characterized by abnormal, recurrent, and delayed reaction to sunlight. […] The prevalence of PMLE is around 10-20% in the general population. It commonly occurs in females between 20 and 30 years of age. It is the most common photodermatosis in school-going children. […] Visible light sensitivity is an important phenomenon in PMLE. It typically presents as recurrent and chronic lesions over photoexposed sites. Initially, patchy erythema occurs with pruritus. […] The unique feature of PMLE in Indian skin is the pigmentary change which varies from hypopigmented to hyperpigmented lesions. These pigmentary changes may occur alone or in combination with erythematous or skin-colored lesions. The pigmentary lesions are seen in more than 50% of lesions.

• #4 Polymorphous Light Eruption– An Indian Scenario

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8088173/

  PMLE is typically characterized by transient, intermittent, and a delayed response at 30 minutes to several hours after UV light exposure resulting in an abnormal cutaneous response. The eruption usually takes up to two weeks to resolve in the absence of further ultraviolet radiation. […] The clinical features of PMLE usually follow a characteristic sequence following sun exposure. It starts with itching followed by the appearance of a patchy erythema. Following this, distinct lesions appear which are sparsely distributed initially, which then coalesce to form densely aggregated lesions. […] The morphological types of lesions noted in the Indian skin are macule, papule, plaque, vesicular, and plaques with lichenification; as isolated lesions or in combinations. […] The histopathology of PMLE is characterized by the presence of hyperkeratosis, spongiosis with or without the presence of liquefactive degeneration in the epidermis. […] The management of PMLE includes both preventive measures and medical management.

• #5 Polymorphous light eruption – Wikipedia

  https://en.wikipedia.org/wiki/Polymorphous_light_eruption

  The rash may persist for many days to a couple of weeks, resolving spontaneously without scarring as long as further sunlight exposure is avoided. […] Recurring yearly, the eruption can sometimes last longer than a few days if persistent and repeated sun exposure occurs. However, the „hardening” effect, with respite during the later summer, frequently occurs with gradual exposure of sunlight, eventually leading to significant improvement. […] The rash is usually quite symmetrical and characteristic for each individual, appearing similar with each recurrence, but can look dissimilar in different people. […] Fever, fatigue and headaches have been previously associated with the eruption, but are rare.

• #6 Polymorphous Light Eruption Symptoms, Causes, and Treatment

  https://www.healthline.com/health/polymorphous-light-eruption

  Symptoms of PMLE usually begin within a few hours to days after sunlight exposure, typically in the spring or early summer. An itchy rash will appear on areas that were newly exposed to the light, including: dcolletage (low neckline), chest, forearms, backs of your hands, lower legs, feet. […] The rash usually doesnt affect the face. While the rash varies from person to person, the particular rash you get will typically be similar every time it happens. […] If you avoid UV light, your rash will heal on its own in a few days to weeks. It wont leave any scarring. […] Its not as common, but you might have additional symptoms, like: fever, headaches, malaise. […] Your first eruption of the year may be the most severe, with following eruptions progressively subtler. […] Polymorphous light eruption is a condition that causes your skin to react to light, usually UV light. Most UV light you are exposed to comes from the sun.

  https://www.healthline.com/health/polymorphous-light-eruption

  When your skin is exposed to sunlight, a rash will form within a few hours or days. Without additional exposure it will heal on its own. […] Women between 20 and 40 with pale skin are the most affected, but anyone can have PMLE. Its most pronounced during the spring and early summer. […] Your skin can build up a tolerance to UV light throughout the summer, but this will go away during the winter.

• #7 Polymorphic light eruption

  https://www.nhs.uk/conditions/polymorphic-light-eruption/

  An itchy or burning rash appears within hours, or up to 2 to 3 days after exposure to sunlight. […] It lasts for up to 2 weeks, healing without scarring. […] The rash usually appears on the parts of the skin exposed to sunlight, typically the head, neck, chest and arms. […] The rash can take many different forms (polymorphic): you may get crops of 2mm to 5mm raised, pink or red spots, but redness may be harder to see on brown and black skin. […] The rash may be a rare occurrence or may happen every time the skin is exposed to sunlight. It ranges from mild to severe. […] If further sun is avoided, the rash may settle and disappear without a trace within a couple of weeks. […] For many people with polymorphic skin eruption, the rash appears every spring and remains a problem throughout summer before settling down by autumn.

• #7 Polymorphic light eruption

  https://www.nhs.uk/conditions/polymorphic-light-eruption/

  Polymorphic light eruption is more common in women than men. […] It usually starts between the ages of 20 and 40, although it sometimes affects children. […] Many people with polymorphic light eruption find their skin improves over the years. […] Your skin may harden (become more resistant to sunlight) during the summer, which means more sun can be tolerated without your skin reacting. […] The rash may even eventually clear up on its own, although this is unusual.

• #9 Polymorphic Light Eruption – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK430886/

  Polymorphic light eruption is the most common form of immunologically mediated photosensitivity dermatoses. Exposure to sunlight in spring or summer results in an irritable rash that resolves within a few days, providing further exposure is avoided. […] The first sign of polymorphous light eruption typically appears after first exposure to intense sunlight during the spring or early summer in temperate climates. Several hours to days later, an irritable rash appears on areas newly exposed to the light such as the décolletage, forearms, backs of hands, lower legs and feet. It rarely affects the face. It also occurs in some patients treated for inflammatory skin diseases with phototherapy, when it may appear on the trunk and proximal limbs. […] The rash persists for several days then clears up without scarring if further exposure to UV is avoided. It may persist for weeks or months if repeatedly exposed, although in most individuals gradual exposure leads to hardening so that the eruption does not occur in late summer. Polymorphic light eruption tends to recur annually and is some patients persists throughout the year, depending on latitude. It often reduces in severity over time and eventually resolves with a lower prevalence in older people.

• #10 Polymorphous Light Eruption: Practice Essentials, Pathophysiology, Etiology

  https://emedicine.medscape.com/article/1119686-overview

  Polymorphous (polymorphic) light eruption (PMLE) is characterized by recurrent, abnormal, delayed reactions to sunlight, ranging from erythematous papules, papulovesicles, and plaques to erythema multiformelike lesions on sunlight-exposed surfaces. […] PMLE can have a substantial psychosocial impact. In a review by Richards et al, as many as 40% of patients described emotional distress related to PMLE. […] Management of PMLE includes strict sun protection. This can be accomplished by using broad-spectrum sunscreens, seeking shade, and wearing protective clothing, including hats. […] Expression of PMLE may range from an insignificant, mild rash to severe disease affecting the patient’s quality of life. Some PMLE patients experience a less severe reaction with each consecutive year, but many patients have reactions that may worsen with time without appropriate treatment. Each case should be evaluated individually. […] PMLE is a chronic condition; the average time to resolution is long and may extend to 30 years. A registry analysis (N = 97) by Gruber-Wackernagel et al determined that 74% of PMLE patients were still experiencing symptoms after 20 years.

  https://www.health.harvard.edu/a_to_z/sun-allergy-photosensitivity-a-to-z

  Symptoms vary, depending on the specific type of sun allergy: […] PMLE typically produces an itchy or burning rash within the first two hours after sun exposure. The rash usually appears on sun-exposed portions of the neck, upper chest, arms and lower legs. In addition, there may be one to two hours of chills, headache, nausea and malaise (a general sick feeling). In rare cases, PMLE may erupt as red plaques (flat, raised areas), small fluid-filled blisters or tiny areas of bleeding under the skin. […] Actinic prurigo (hereditary PMLE) Symptoms are similar to those of PMLE, but they usually are concentrated on the face, especially around the lips. […] Photoallergic eruption This usually causes either an itchy red rash or tiny blisters. In some cases, the skin eruption also spreads to skin that was covered by clothing. Because photoallergic eruption is a form of delayed hypersensitivity reaction, skin symptoms may not begin until one to two days after sun exposure.

  Polymorphous light eruption, or PLE, is the most common skin disease caused by sunlight. PLE arises spontaneously in people who are sensitive to ultraviolet light and is characterized as one type of photodermatosis. It usually manifests as an itchy rashlittle red bumps or slightly raised patches of skinafter sun exposure in people who are photosensitive. While the rash can take different forms in different people, it usually appears the same in each individual. PLE is more likely to appear when the skin isnt used to sunshine, such as in spring or on a sunny holiday. While the sun rash can go away on its own, it tends to reappear after the first incident. PLE is not harmful or infectious, but may be unsightly and embarrassing. […] The rash usually appears on the parts of the skin exposed to sunlightthe head and neck, chest, and armsbut which might not be exposed year-round. An itchy or burning rash may appear anywhere from hours (or even minutes) up to two to three days after sun exposure. The sun rash may consist of erythematous papules, papulovesicles, plaques and/or lesions similar to eczema or erythema multiforme, and may be confused with hives. It can look like dense clusters of small red bumps and raised rough patches. Some lesions may have fluid-filled blisters. An eruption may last up to two weeks but heal without scarring if sunlight is avoided. However, if the skin is exposed to additional sunlight before the rash has healed, the condition usually gets much worse.

  Although there isnt really a treatment that permanently gets rid of PLE, the outlook is good. Even though rashes may be unsightly and uncomfortable, they normally heal completely. For most people, PLE is a condition that can be managed with lifestyle changes and various over-the-counter sun rash treatments and natural remedies. […] PLE tends to reoccur each year, but throughout the year, individuals with PLE can usually tolerate more sun exposure as the summer progresses and they build up some resistance to UV rays. This means that individuals can be in the sun longer before they develop a skin reaction, and by staying under this threshold of sun exposure they can prevent reactions. PLE doesnt usually show up during the winter but can in individuals who are very sensitive to sunlight.

• #15 Polymorphic light eruption – BAD Patient Hub

  https://www.skinhealthinfo.org.uk/condition/polymorphic-light-eruption/

  The term light eruption means a rash that comes up after exposure to light. Polymorphic is two words; poly means many, and morphic means forms. In other words, the rash of PLE can take on many different forms, including small red bumps, larger red areas, and blisters. In PLE, a rash with one or more of these components comes up a day or two after exposure to the sun. PLE is the most common rash caused by UV light, perhaps affecting up to 10%-20% of the population in western countries. It tends to be more common in the spring or early summer. […] The rash (pink or red spots) of PLE can itch or have a burning sensation. PLE can be embarrassing as it comes up on exposed areas of skin. PLE restricts outdoor activities and holidays in the sun. […] PLE ranges from a mild rash that lasts for only a short time to a severe and extensive eruption affecting the quality of life. The rash comes up equally on both sides of the body, affecting mainly those parts of the skin that are kept covered in the winter, such as the arms, the upper thighs and the upper trunk. For this reason the face, neck and backs of the hands are sometimes, but not always, affected. The appearance of the rash varies from person to person. The most common type has large numbers of small red bumps. In other people the rash is made up of larger red areas and small blisters. The rash of each affected person usually looks the same each time it comes back to that particular person. The rash usually disappears by itself within 7-10 days, if there is no further exposure. It heals without scaring.

  Polymorphous light eruption is a condition that typically begins after intense sunlight exposure, especially during the spring or early summer in temperate climates. The first sign is a rash that appears on parts of the body that have recently been exposed to sunlight including the lower legs, backs of hands, forearms, and upper chest. It rarely affects the face. […] The rash can take on many forms, which can vary from person to person. The most common is a red bump-like rash that can sometimes merge to form larger skin patches. Other possible types include flat skin discolorations, blisters, plaques similar to skin lichen, itch-inducing bumps, and ring-like lesions that can look like another skin condition called erythema multiforme. […] While quite rare, some people might experience symptoms beyond the skin, such as fever, fatigue, and headaches.

• #16 Polymorphic Light Eruption (Sunlight Sensitivity) – MD Searchlight

  https://mdsearchlight.com/skin-problems-and-treatments/polymorphic-light-eruption-sunlight-sensitivity/

  Generally, the rash goes away on its own after several days, as long as one avoids additional UV exposure. However, continuing exposure can cause the rash to last for weeks or even months. The good news is that most people become less susceptible to the rash after gradual sun exposure over the season, making the condition less likely to occur in the late summer. […] This condition usually comes back every year and, for some people, might persist throughout the year depending on how close they live to the equator. However, the severity often lessens over time and becomes less common as people get older.

  https://www.contemporarypediatrics.com/view/juvenile-spring-eruption-in-a-young-boy

  With Juvenile spring eruption (JSE), exposure to sunlight in early spring or summer results in a papulovesicular rash that usually resolves within 1 to 2 weeks. […] The child typically presents with multiple red, edematous papules that may become vesicular and crusted on the helices of the ears. […] The lesions do not recur until the following spring. […] JSE is seen typically in boys and young men in early spring. […] It is suggested that it occurs as a delayed hypersensitivity reaction to an endogenous antigen expressed after exposure to sunlight or artificial sources of radiation. […] Classic PMLE can occur over the face, the V area of the chest, the back of the neck, and the dorsolateral aspects of the forearms. […] Recurrent, unprotected sun exposure may result in recurrent lesions in cases of PMLE, which often settles down later in the summer.

• #18 Polymorphic Light Eruption (PMLE): Symptoms and Treatment

  https://patient.info/skin-conditions/sun-and-sunburn/polymorphic-light-eruption

  Polymorphic light eruption (PMLE) is a rash which comes on after being in strong sunlight. […] It looks like reddened skin with raised red spots or small blisters. It is generally itchy and uncomfortable. It can feel sore or burning. It occurs most often on areas of skin that haven’t seen the sun for a while – it is more common on the arms and the chest than on the face or the hands. It can take as little as 20 minutes of strong sun to trigger the rash. The rash generally comes on within a few hours of going into the sun. The rash usually gets better within a few days. The rash heals completely, without scarring. […] The rash generally clears up within a week if you stay out of the sun. However, if you get more sunshine on your skin then it is likely to get worse. The rash may come back if you go into strong sun again. However, symptoms tend to improve during the summer, as your skin becomes more adapted to sunlight.

• #18 Polymorphic Light Eruption (PMLE): Symptoms and Treatment

  https://patient.info/skin-conditions/sun-and-sunburn/polymorphic-light-eruption

  Some people get PMLE each year. It starts each spring with a rash that lasts for up to a week, and then comes back if you go out in the sun again. But it is usually less severe each time it comes back. […] Although no treatment stops polymorphic light eruption (PMLE) developing for ever, the outlook is good. The rash heals completely, although while it lasts it may be uncomfortable or unsightly. For most people, PMLE tends to follow a pattern and it usually comes back each year when you first get exposed to strong sunshine. Over time you learn how much sun your skin can tolerate and you should try to keep within that limit to avoid PMLE. You will learn to introduce your skin to sunlight gradually in the spring. For some people, PMLE may improve or clear up completely over the years. PMLE also tends to improve for women after the menopause (when menstrual cycles stop at around the age of 50).

• #19 Polymorphous Light Eruption Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/1119686-clinical

  Polymorphous (polymorphic) light eruption (PMLE) tends to manifest in the spring and early summer; it may also manifest in the winter involving the face as a result of sunlight reflected off snow. In addition, PMLE is a recurrent condition, and patients typically state that they have had the eruption before and that it went away as time passed. […] In most cases, the lesions of PMLE first erupt after exposure to strong sun following a period of relative photoprotection for example, at the onset of a vacation in a sunny place or at a high altitude in early spring. The eruption decreases in severity as the summer progresses. […] The onset of the disease is sudden. The accompanying rash is pruritic and, in some instances, painful. Triggering of the eruption takes 30 minutes to several hours of sun exposure. The rash appears within hours to days of exposure, and it usually subsides over the next 1-7 days without scarring, though in some cases it has been reported to persist for as long as 5 weeks.

• #19 Polymorphous Light Eruption Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/1119686-clinical

  Most patients have associated pruritus; some describe stinging and pain. […] Occasionally, patients experience systemic flulike symptoms after sun exposure. […] A study (N = 138; 85 females, 53 males) by Jansn traced the natural history of chronic PMLE for 10.5 years. In 57% of cases, PMLE developed rapidly. Lesions often began in a small photoexposed area and extended to a larger area each year. Light sensitivity tended to increase with each subsequent year. In 50% of patients, yearly hardening phenomena occurred. Ocular and oral involvement were noted in 46% and 49% of patients, respectively. About 66% patients experienced some general symptoms after solar radiation exposure.

• #20 Polymorphic Light Eruption (PMLE): Causes and Treatment

  https://patient.info/doctor/polymorphic-light-eruption-pro

  PMLE usually presents in the spring or during travel to a sunny location. The rash varies (as its name suggests) but usually follows the same pattern in each individual: […] The typical history is sudden onset of a rash 30 minutes to 24 hours after sun exposure at the start of the sunny season. The rash subsides over about a week (unless there is continuing exposure). Symptoms can recur, but reduce as summer and sun exposure progress. […] The most common form of rash is crops of pink or red, raised spots of 2-5 mm on the arms, chest or lower legs. Usually the face is spared. […] The rash is usually itchy or 'burning’. […] There is occasionally a systemic flu-like illness. […] In most, the rash settles in a few days to two weeks. […] It may or may not recur next time the sun shines on the skin.

• #20 Polymorphic Light Eruption (PMLE): Causes and Treatment

  https://patient.info/doctor/polymorphic-light-eruption-pro

  If the rash gets more sun exposure before it has cleared, the condition tends to worsen. […] In most individuals there is a 'hardening’ as the summer progresses and tolerance to sun increases. However, this does not always occur. Some people can develop PMLE even in the winter. […] Most people are not severely affected and may not consult about their symptoms. […] The condition is likely to ease as the spring and summer advance; however, it will probably recur the following year unless precautions are taken. […] Long-term prognosis – PMLE often improves over time (years) and may resolve in some patients.

  Polymorphous Light Eruption (PMLE) is a sensitivity to the sun, commonly referred to as a sun allergy. In sensitive individuals, this photosensitivity causes a red and itchy rash, typically on the neck and upper chest, limbs and anywhere the skin is exposed to direct sunlight. […] When affected by this issue, you may notice several symptoms, ranging from very mild to more severe. If you believe you may have this condition, be alerted to the more common symptoms such as: A burning sensation on the affected area or areas of the skin, Itching, which may range from mild or moderate to severe, A red rash or welts on the affected area, Blisters in more severe cases, Pinpoint papules or lesions, Dermatitis (flaky and dry patches of skin). […] If you are experiencing symptoms that have caused much discomfort and seems to reoccur, you might need to be treated by a dermatologist. However, he or she will need to make a conclusive diagnosis before recommending a treatment plan. If you have experienced severe symptoms such as blistering and hives, a skin biopsy may be performed. Once a diagnosis of PMLE has been determined by your doctor, you may be told to try a few at-home remedies or treatments. This may include the use of a cool compress to the affected area or the use of over-the-counter antihistamines to reduce the inflammation. Itchy skin may be relieved by the use of topical anti-itch creams or lotions. If the above mentioned home remedies do not provide relief, the doctor may prescribe a full-strength antihistamine or oral steroids. These may reduce inflammation. If your skin becomes infected, you may need to be given prescription antibiotics. […] Although considered rare, your skin may become infected if you scratch the affected areas and break the skin. Signs of an infection include oozing, drainage or pus from the area, fever and chills, as well as pain and redness. If this occurs, see your dermatologist at once.

• #22 Polymorphous light eruption: Pictures and treatments

  https://www.medicalnewstoday.com/articles/polymorphous-light-eruption

  Polymorphous light eruption (PLE) is a common skin rash that occurs due to sunlight exposure. PLE causes small bumps or raised plaques on the skin. […] The rash typically lasts only 23 days, but some people may continue having symptoms throughout summer. […] PLE symptoms typically appear around 2 hours after sun exposure and last for several days before improving on their own. Some people may experience symptoms for longer than this, potentially all summer if they continue getting sun exposure, but this is uncommon. […] When the condition first appears, the most common symptoms include: burning, itchiness, and redness, in lighter skin tones.
