Idiopathic Calcinosis Cutis of the left great toe-A case report

Abstract

Calcinosis cutis, a rare benign disorder, involves systemic calcium deposition in soft tissues, often linked with autoimmune and renal disorders. Pathophysiology varies among its five main types: dystrophic, metastatic, idiopathic, iatrogenic, and calciphylaxis. Dystrophic calcification, the most common type, is associated with normal calcium and phosphorus levels and autoimmune diseases. Metastatic calcification, on the other hand, arises from abnormal serum calcium and phosphorus levels. Idiopathic calcification lacks underlying tissue damage or abnormal laboratory values. Iatrogenic calcification was triggered by calcium or phosphate-containing substances. Calciphylaxis involves vessel calcification and is linked to chronic renal failure and dialysis. A 19-year-old female presented with pain and swelling on her left great toe plantar aspect, diagnosed as unilateral idiopathic calcinosis cutis. A comprehensive diagnostic approach, including histopathological, radiological, and blood investigations, is crucial for effective management. The study aimed to highlight idiopathic cutaneous calcinosis, emphasizing its accurate diagnosis through clinical, pathological, and metabolic correlation. Surgical excision offers a complete cure for this rare condition, leading to an excellent prognosis.
