Calcinosis cutis is a condition of accumulation of calcium salts within the dermis. We are presenting four cases of calcinosis cutis, with different clinical presentations, occurring in healthy individuals, with normal serum calcium and phosphorus levels. Histologically, all cases showed similar morphology, the lesions were composed of large and small deposits of calcium. Foreign-body giant cell reaction was seen in one case. Another case had intact and ruptured epidermal cysts and calcification within the cyst.

Introduction: Tumoral calcinosis is a rare hereditary condition characterized by the deposition of calcium phosphate and hydroxyapatite in periarticular soft tissues. First described by Giard and Duret in 1898 and later detailed by Inclan in 1943, this condition has often been confused with other forms of periarticular calcification. Tumoral calcinosis predominantly affects young males and is typically found around major joints, such as the shoulder, elbow, hip, ankle, and wrist.

Calcinosis cutis affects 20-40% of patients with systemic sclerosis. This study tests the hypothesis that calcium-chelating polycarboxylic acids can induce calcium dissolution without skin toxicity or irritancy. We compared citric acid (CA) and ethylenediaminetetraacetic acid (EDTA) to sodium thiosulfate (STS) for their ability to chelate calcium in vitro using a pharmaceutical dissolution model of calcinosis (hydroxyapatite (HAp) tablet), prior to evaluation of toxicity and irritancy in 2D in vitro skin models.
