  Calciphylaxis, also known as calcific uremic arteriolopathy, is a rare but potentially devastating condition most often observed in patients with end-stage renal disease, although it does occasionally develop in patients without renal failure. It is characterized by cutaneous arteriolar calcification and subsequent tissue ischemia and infarction and causes painful skin lesions. Calciphylaxis is associated with substantial morbidity due to severe pain, non-healing wounds, and frequent hospitalizations. It is a highly fatal condition with 1-year mortality rates greater than 50 percent, most frequently due to sepsis. […] Calciphylaxis typically presents with extremely painful ischemic cutaneous lesions or painful subcutaneous nodules without skin changes, although at times, pain may precede the development of the lesions. Skin lesions often appear as violaceous or erythematous subcutaneous nodules and plaques. Livedo reticularis can also result from ischemia. As the lesions progress, they may become ulcerated with the development of necrosis, eschar, and infection. Proximal areas with increased adipose tissue such as the abdomen, thighs, and buttocks are most commonly involved, although distal sites such as the digits can also be affected. Extreme pain is a hallmark of calciphylaxis leading to considerable morbidity.

• #3 Calciphylaxis: Symptoms & Causes

  https://my.clevelandclinic.org/health/diseases/22359-calciphylaxis

  Calciphylaxis can look different depending on its severity. […] Symptoms of calciphylaxis may include: Pain. Most cases of calciphylaxis are very painful. The sensation of pain may start before lesions or any other visible signs appear. The affected areas can also become hypersensitive to pressure or touch, making the pain more intense. […] Lesions (earlier stages). These are areas of skin that turn red, purple, brown or black. These lesions usually have a netlike appearance. They may also blister, and the affected area of skin may become hardened and leathery. […] Ulcers and wounds (later stages). Lesions usually become wounds that spread outward in starlike shapes. The wounds often have a foul smell. Areas of dead skin and flesh may turn black and take on a scab-like appearance and fall off.

[…] Symptoms of calciphylaxis are distinctive. Most patients suffering from this disease will show these symptoms: […] Extreme pain. Patients may complain about pain in their skin before there are any visible signs of calciphylaxis. This is one of the first symptoms most people will experience. […] Purple or red skin markings. These markings will usually form a web or net-like pattern on the skin and be very painful. In the earlier stages, they will be purple or red. Later, they may change to brown or black. The texture of the skin can also change by becoming hard and leathery or blistered. […] Sores that dont heal. The blister sites will turn into lesions on the skin. These sores develop black or brown crusts that are extremely painful. They will usually start to develop a star-shaped pattern and putrid smell. Crusted parts of the lesions tend to fall off, but the wound will continue to grow.

  https://dermnetnz.org/topics/calciphylaxis

  Calciphylaxis begins as surface purple-coloured mottling of the skin (retiform purpura) then bleeding occurs within the affected area. There may be blood-filled blisters. The skin goes black in the centre of star-shaped (stellate) purple lesions. The skin cells die because of lack of blood supply (dry gangrene). This causes deep and often extensive ulcers. Surgical intervention may aggravate ulceration. […] Patients with calciphylaxis usually experience severe pain, burning and sometimes itching at the lesion sites. […] Calciphylaxis most often occurs on the lower limb where it is one of the causes of blue toe syndrome. Lesions on the fatty areas of the trunk, abdomen, buttocks, or thighs appear to be more dangerous than lesions on the lower legs and feet. […] Calciphylaxis can lead to: Chronic and extensive ulceration, Secondary infection with sepsis, Death.

  https://www.ccjm.org/content/83/8/562

  A 53-year-old woman presented with extensive, nonulcerated, painful plaques on both calves. […] The patient presented with extensive necrotic, leathery, violaceous lesions on both calves that resembled eschar. […] In the early stages, lesions of calciphylaxis are focal and appear as erythema or livedo reticularis with or without subcutaneous plaques or ulcers. As the disease progresses, the ischemic changes coalesce to form denser violaceous, painful, plaquelike subcutaneous nodules with eschar. In the advanced stages, the eschar or ulceration involves an extensive area. […] In the advanced stages, the diagnosis of calciphylaxis is clinically more evident, and the differential diagnosis usually narrows. Well-demarcated, necrotic, indurated lesions that are bilateral in a patient with end-stage renal disease without shock makes the diagnosis very likely.

• #10 Calciphylaxis – Wikipedia

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

  Calciphylaxis is characterized by painful skin lesions. […] The first skin changes in calciphylaxis lesions are mottling of the skin and induration in a livedo reticularis pattern. As tissue thrombosis and infarction occurs, a black, leathery eschar in an ulcer with adherent black slough develops. […] These lesions are always extremely painful and most often occur on the lower extremities, abdomen, buttocks, and penis. […] Because the tissue has infarcted, wound healing seldom occurs, and ulcers are more likely to become secondarily infected. Many cases of calciphylaxis lead to systemic bacterial infection and death. […] Overall, the clinical prognosis for calciphylaxis is poor. The 1-year mortality rate in patients who have end-stage kidney disease is 45-80%. […] Median survival in patients who do not have end-stage kidney disease is 4.2 months. […] The most common cause of death in calciphylaxis patients is sepsis, severe infection originating from a non-healing ulcer.

  Calciphylaxis occurs when skin cells die due to a lack of blood supply. Symptoms include blisters, bleeding, and pain. […] Calciphylaxis causes painful, blood-filled lesions to form on the skin. It mainly affects people with end-stage kidney disease. […] Many cases of the condition can have fatal consequences. Other cases lead to nonhealing wounds and frequent hospitalizations. […] Calciphylaxis is a potentially fatal condition with a 1-year mortality rate of over 50%. This means more than half of all people with the condition may die within a year. […] Calciphylaxis lesions usually have the following features: Location: Calciphylaxis patches most commonly form on the lower limbs. However, they can also appear on the trunk, abdomen, buttocks, or thighs. Color: Calciphylaxis often begins as a purple-colored patch or blotch. It also typically causes the skin to become dark. Blistering: The patches typically turn into blood-filled blisters and then ulcers over time. Distribution: The ulcers can grow deep into the skin and become extensive. Pain: Extreme pain is common with calciphylaxis. Other sensations: Severe burning and itching may also occur at the sites of the lesions. Syndrome: Calciphylaxis can cause blue-toe syndrome, which causes muscle pain in the legs and severe pain in the foot.

  https://emedicine.medscape.com/article/1095481-overview

  Calciphylaxis (also referred to as calcific uremic arteriolopathy) is a poorly understood and highly morbid syndrome of vascular calcification and skin necrosis. […] The pathogenesis of calciphylaxis remains obscure and is likely the result of a multiplicity of comorbid factors or events. […] The clinical appearance of the lesions of calciphylaxis (livedo reticularis and stellate purpura) suggests that the common endpoint of the process is small-vessel occlusion. Indeed, microthrombi are found in most cases. […] The prognosis is generally not good, with mortality as high as 60-80% having been reported in patients with ulcerative disease. […] Mortality is higher in patients with proximal disease than in those with only distal or acral disease.

  Calciphylaxis, also known as calcific uremic arteriolopathy, is a rare syndrome that typically causes skin necrosis and usually affects dialysis patients. […] From a clinical point of view, calciphylaxis may progress from painful purpura to extensive areas of skin necrosis that can potentially lead to superinfection and the death of the patient due to sepsis. […] It is usually manifested in two phases; first, cutaneous erythema and pruritus and the second with very painful ulceration and skin necrosis. The latter is associated with a high mortality rate. […] The distribution of the lesions may be proximal (areas with more adipose tissue) or distal which is the most frequent and with a better prognosis. […] Mortality is between 30% and 80% depending on the comorbidities and the configuration of cutaneous involvement. In recent years, mortality seems to have improved, especially since the pathology is better known, action is taken more quickly and some treatment alternatives are available.

  Calciphylaxis, a multifactorial cutaneous vascular disease, is a rare but therapy-resistant and life-threatening disorder that usually occurs in patients with end-stage kidney disease (ESKD). […] Clinically, calciphylaxis is characterized by chronic, painful, and non-healing wounds. […] Approximately 50% of patients with calciphylaxis are bedridden or wheelchair-bound, and more than 70% require hospitalization because of severe ulcers. […] The pathophysiology of calciphylaxis is complex, and it is believed to have several causative factors. […] Calciphylaxis is also known by the alias calcific uremic arteriolopathy, since the accumulation of uremic toxins is believed to be involved in the pathogenesis of this condition. […] Generally, appropriate management of Ca-P metabolism is recognized to be important in the treatment of calciphylaxis.

  Stages of Calciphylaxis Progression As calciphylaxis progresses, it goes through distinct stages, each with its own set of symptoms and potential complications. By recognizing these stages, individuals and healthcare providers can take proactive steps to prevent further deterioration and seek timely treatment. […] Calciphylaxis is a rare but serious condition characterized by the development of skin lesions, pain, and tissue necrosis. Early recognition of these symptoms is crucial to prevent further complications and facilitate prompt medical intervention. By understanding the common signs and symptoms of calciphylaxis, individuals at risk or experiencing these symptoms can seek appropriate care. […] Common symptoms of calciphylaxis include painful skin lesions, skin discoloration, non-healing wounds, and necrosis. Some individuals may also experience fever, malaise, and weight loss. It is important to recognize these symptoms early and seek medical attention to prevent further complications.

  Calciphylaxis is a poorly understood disorder in which calcification of small blood vessels causes painful ischemic skin and visceral lesions most often in patients with end-stage renal disease (ESRD). […] Calciphylaxis occurs in 4% of ESRD patients on peritoneal dialysis or hemodialysis and can occasionally occur in pre-dialysis renal disease. […] Over time this process likely precipitates arteriolar remodeling and progressive stenosis, causing ischemia and skin infarcts. […] The one-year mortality rate for calciphylaxis is estimated to be 45-80%, which may be even higher when ulcerative skin lesions are present. […] Early signs include pain and a lace-like purplish discoloration of the skin (livedo reticularis). This is often followed by painful subcutaneous nodules or plaques that progress to necrotic ulcerations. […] Areas of greatest fat tissue — abdomen, buttocks, and inner thighs — are most commonly involved, although visceral organs, skeletal muscle, and heart muscle can also be affected. […] Calciphylaxis can be challenging to distinguish from a vasculitis.

• #43 Calciphylaxis Diagnosis and Management in Primary Care

  https://www.clinicaladvisor.com/features/calciphylaxis-diagnosis-treatment-primary-care/

  A 54-year-old man presents to a hospice inpatient unit for pain management and wound care. The patients medical history includes end-stage renal disease (ESRD), calciphylaxis, and type 2 diabetes. Review of his medical history reveals that the patient initially presented 6 months prior with superficial reddening of the skin. […] The reddening rapidly progressed into nonhealing ulcers and the patient underwent above the knee amputation. […] Skin changes associated with calciphylaxis have sudden onset and progress rapidly to open ulcerations and then necrosis. […] A painful necrotic ulcer covered with black eschar that started as painful ecchymoses is usually the presenting symptom; patients often mistake initial reddening for a bruise and delay seeking medical care. […] The presence of malodorous, dusky, and/or necrotic lesions should increase suspicion of calciphylaxis.

  A 49 year-old obese man with non-alcoholic steatohepatitis and cirrhosis, complicated by hepatorenal syndrome not on dialysis, was admitted for expedited liver transplant workup. On admission, he was found to have the lower extremity skin lesions shown below. He noted that these slowly-enlarging lesions had developed over the past 2 months and were extremely tender, requiring opiates to control the pain. […] The lesions of calciphylaxis normally involve tissue with high adiposity, such as the buttocks, thighs and lower abdomen. Localized livedo reticularis may the first sign on exam. Lesions progress from subcutaneous plaques to open ulcerations, necrotic ulcers, and ultimately eschars with a high-risk for secondary bacterial infection. The condition is usually limited to the skin and subcutaneous soft tissues, although occasionally patients can have deeper muscle involvement with frank weakness on exam. The skin lesions themselves are extremely painful and do not heal on their own.

  In the present case, appropriate management of Ca-P metabolism led to regression of the ulcers. […] With this therapy, her painful and severe skin ulcers dramatically regressed in only 3 months. […] Therefore, we suggest that intensive management of Ca-P metabolism is essential to prevent the development of calciphylaxis. Hypercalcemia or hyperphosphatemia due to excess VDRA therapy could be an aggravating factor for calciphylaxis in CKD patients on HD.

  White blood cell count levels higher than 15,000 cells/mm3 have been associated with a worse prognosis. […] The mean age is 48 years (ranging from 6 months to 83 years). […] A higher incidence has been suggested in women and Caucasian individuals. […] Other risk factors include hyperparathyroidism, end-stage renal disease of any etiology, elevated calcium-phosphate product, and vitamin D exposure. […] Additionally, obesity, diabetes, liver disease, immunosuppression, lymphoma, blood transfusions, serum aluminum, hypoalbuminemia, calcitriol, HIV, systemic corticosteroids, and local trauma may trigger calciphylaxis in patients who are already predisposed. […] Mortality ranges between 60-87%. […] Calciphylaxis is a heterogeneous disorder with a seemingly multifactorial etiology, and therefore response to treatment is variable.

  The IL6 pathway is central to skin lesion development in calciphylaxis, a CKD-related condition, and blocking it may prevent ulcers and pain. […] Calciphylaxis is marked by painful skin ulcers and is common in end-stage kidney disease, with no current cure. […] The findings showed that the IL-6-tissue factor (TF)-inducing ability of calciphylaxis serum was an activity marker and IL-6 as a therapeutic target for uremic calciphylaxis. […] This study reveals the presence of a pathological and harmful cycle between the fat under the skin, sweat glands, and small blood vessels that keep feeding onto itself. If this cycle isn’t stopped and remains unchecked, it will lead to the skin ulcers that won’t heal. […] Those drugs are likely to prevent progression of the skin ulcers and resolve the pain that we see in patients with calciphylaxis.

  Calciphylaxis causes ischemia in multiple organs and skin ulcers owing to progressive calcification in small and medial arteries. […] Here, we present a case of calciphylaxis associated with a wide range of symptoms, including lower thigh skin ulcers, a rectovaginal fistula, and femoral neck fracture. […] The patient started hemodialysis in 2005 for chronic renal failure, and she experienced symptoms associated with hyperparathyroidism complications in 2013. […] She visited our department for an initial examination in June 2015, with the chief complaint of intense pain and purpura in both lower thighs. […] Subsequently, the purpura spots rapidly formed ulcers, and she was hospitalized urgently. […] Clearly demarcated ulcers with yellow gangrenous tissue were observed on her right ankle and several areas of her left leg.

  Cutaneous calciphylaxis refers to the skins lesions that are seen in the disease process, but vascular calcifications and associated complications can present in other organs, such as the skeletal muscle, lungs, eyes, and the brain. […] Pain in cutaneous calciphylaxis (CP) can be severe and debilitating; proper treatment requires a multi-specialty approach. […] The progression of these plaques to an ulcerated state dramatically increases the mortality rate associated with the disease (from 33% to above 80% at 6 months upon development of ulceration). […] Cutaneous lesions manifest in a significant number of patients, such as nodules, plaques, purpura, and ulcers. […] These cutaneous lesions have the potential to be extremely painful and difficult to treat. […] Currently, skin biopsy with histological examination is the best method of diagnosing the disease, with medical imaging being helpful in select cases. […] Treatment of pain must be multimodal and should target the underlying disease etiology, as pain is often associated with the primary disease burden. […] Currently, there are multiple clinical trials in progress in order to provide relief to patients with this debilitating disease.

  A rare vascular calcification disorder typically characterized by occlusion of microvessels in the cutaneous tissue resulting in painful cutaneous lesions. The disorder is often life-limiting. […] Calciphylaxis typically affects patients with end-stage kidney disease (ESKD) treated with dialysis. […] The average age at the time of diagnosis is reported between 50 to 70 years; very few patients are children. Patients with calciphylaxis typically present with painful skin lesions. The pain is typically severe and there is associated tactile hyperesthesia. The initial manifestations may include skin induration, plaques, nodules, livedo, or purpura. The initial lesions rapidly progress to stellate ulcers with black eschars. Sepsis originating from the resultant wounds is considered the most common cause of death. Rarely, diffuse precipitation of calcium in viscera occurs (mainly in the heart or lungs, but also in the stomach or kidneys) which may lead to fibrosis and thrombosis, and eventually tissue necrosis. Depending on the affected organ, patients may present with dyspnea, cough and respiratory failure or acute heart block and subsequent sudden cardiac death. More than 70% of patients with calciphylaxis require hospitalization for severe ulcers. […] Quality of life of patients with calciphylaxis is extremely poor. Once calciphylaxis develops then the patients suffer from substantial morbidity related to pain, wounds and limited mobility, and many die within the first year of disease onset.

  A 45yearold man with diabetes mellitus and hypertension presented with acute renal failure and multiple lesions on his penis and lower extremities. His lesions worsened despite initiation of hemodialysis and sodium thiosulfate. He developed autoamputation of the tip of his penis. Calciphylaxis is a rare disorder with significant morbidity and mortality. It affects up to 4% of patients with endstage renal disease. The lesions are characterized as systemic medial calcification of the arterioles leading to ischemia and necrosis in increased areas with adipose tissue. An elevated calcium phosphate level (55) or parathyroid hormone level can cause calciphylaxis with variability. Parathyroidectomy can decrease the disease progression. Mortality rate is 50% in the first year and overall is 80%. […] Hospitalists care for many patients with endstage renal disease and need to be cognizant of calciphylaxis given its significant morbidity and mortality. Diagnostic evaluation and special care with skin integrity and treatments should be initiated immediately.

  A 65-year-old man with a medical history significant for chronic kidney disease (CKD) and currently on hemodialysis (HD), hyperlipidemia, heart failure with reduced ejection fraction presented to the emergency department with complaints of penile pain for the previous 2 weeks. Initially, the patient noticed a bump in the area around the glans penis and gradually progressed to the extent that the entire area was red, black, and extremely tender. […] Examination of the penis revealed a violaceous, painful, ischemic lesion over the glans. […] Painful cutaneous lesions are the primary presentation of this condition. […] Ultimately these lesions become non-healing ulcers. […] Although rare, penile calciphylaxis is well-described with close to 50 cases reported and less than half of these presenting with isolated penile calciphylaxis. […] Calciphylaxis has an estimated six-month mortality of 50 percent and must be promptly recognized by clinicians.

  Calciphylaxis may manifest as rapidly progressive, diffuse and extensive, cutaneous necrosis, as is seen in this patient with chronic renal failure. Bullae may also be seen as a rare manifestation of calciphylaxis. […] Plain radiography uniformly demonstrates an arborization of vascular calcification within the dermis and the subcutaneous tissue. […] A mixed inflammatory infiltrate frequently occurs. Subcutaneous calcium deposits with panniculitis and fat necrosis may sometimes be found. Vascular microthrombi are frequently evident. […] Serial bone scanning may also be useful for monitoring progression or regression of disease.

  The skin biopsy would confirm the diagnosis of calciphylaxis. The tissue sample should be obtained from the edges of the lesion to avoid necrotic tissue, as this may spoil the diagnosis, but it cannot be taken too far away from the edge because in this case it may result in false negatives. […] The classic anatomopathological findings are defined by the calcification of the tunica media of arterioles from the cutaneous or subcutaneous fat tissue, associated with an important fibro-intimal thickening that decreases the lumen of the vessel which is associated to thrombosis of residual lumen in some vessels.

  Calciphylaxis, or calcific uremic arteriolopathy, is a rare disease characterized by calcification of the arterioles and capillaries in the dermis and subcutaneous tissue, resulting in thrombus formation and subsequent skin ischemia and necrosis. […] Calciphylaxis often presents as cutaneous lesions of livedo reticularis, plaques, nodules and ulcers due to ischemia of the microvasculature. […] Plaques or nodules are the most common presenting lesions, which may be confused with cellulitis because both lesions can present with erythema, pallor and tenderness. […] Patients may have advanced disease, however, once the diagnosis is officially made.
