BACKGROUND Calcinosis cutis, a disease characterized by the presence of calcium deposits in the skin, is classified into four types according to etiology: dystrophic, metastatic, iatrogenic and idiopathic. The dystrophic form is the most common while the idiopathic one is the rarest, but specific incidence and frequency data are not available in scientific literature. OBJECTIVE Calcinosis cut...

Iatrogenic calcinosis cutis presents with similar symptoms and signs of soft tissue, joint and bone infections. We present here a preterm infant with iatrogenic calcinosis cutis misdiagnosed as septhic arthritis and osteomyelitis. We hope that our case report helps to raise clinicians’awareness of this rare situation. .When swelling and erythema of extremities occur in a newborn infant after in...

We report a case of idiopathic calcinosis cutis diagnosed by fine needle aspiration cytology in a 50-yr-old female who presented with a subcutaneous swelling near the left iliac crest. Cytological finding of amorphous calcium salts with histiocytes and the appropriate clinical background led to the cytodiagnosis of idiopathic calcinosis cutis as subsequently confirmed on histopathology. Pitfall...

Calcinosis cutis is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin in various parts of the body. Four main types of calcinosis cutis have been recognized according to etiology: associated with localized or widespread tissue changes or damage (dystrophic calcification), that associated with an abnormal calcium and phosphorus metabolism (metastatic calcificati...

BACKGROUND Calcinosis cutis is usually seen in long standing and untreated cases of juvenile dermatomyositis. CASE CHARACTERISTICS 7-year-old girl with severe calcinosis cutis who developed cutaneous ulceration, rash and myopathy. OBSERVATION Myopathic changes in EMG, muscle edema in MRI, elevated muscle enzymes and Jo-1 positive antibodies. OUTCOME Treatment with prednisolone and methotr...

Calcinosis cutis is an uncommon disorder characterized by the progressive deposition of crystals of calcium phosphate (hydroxyapatite) in the skin in various areas of the body. It is classified into four types according to etiology, namely as dystrophic if calcium and phosphorus levels are normal and tissue damage is present, as idiopathic if calcium and phosphorus levels are normal and no tiss...

Calcinosis cutis is a rare disorder characterized by the deposition of calcium in the skin and subcutaneous tissue. Unilateral idiopathic calcinosis cutis has only rarely been reported in the literature. Here, we report the case of a 7-year-old healthy girl who presented with multiple asymptomatic hard nodules on the right side of her body. Histopathological, radiological, and extensive blood i...

Calcinosis cutis is a rare condition characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. Dystrophic calcinosis cutis appears as a result of local tissue damage or abnormalities, such as alterations in extracellular matrix proteins or subcutaneous tissue with normal calcium and phosphate serum levels. It has been rarely described as a late complication...

Calcinosis cutis is a condition characterized by the deposition of calcium salts in the skin and subcutaneous tissues, and patients suffering from it encounter various connective tissue disorders, such as dermatomyositis (DM), scleroderma, and systemic lupus erythematosus. Although calcinosis cutis is frequently accompanied by juvenile dermatomyositis, rare cases have been reported in adult pat...

The most widely accepted classification of calcinosis cutis is reviewed and several aspects of it are examined. The main point of our criticism is that entities from different groups overlap. Also, the classification mixes etiopathogenic criteria with morphological or semiologic ones. Moreover, the role of the dermatopathologist is limited many times, since only generic information under the di...
