Idiopathic Scrotal Calcinosis.

Idiopathic scrotal calcinosis (ISC) is a rare benign condition which presents with multiple, asymptomatic, and painless nodules on the scrotal skin wall. The lesions have been attributed as sebaceous cysts, calcified steatocystoma, fibroma, atheroma, and xanthoma. Shapiro et al. reviewed the histologic data and found no evidence of an epithelial lining, residual cysts, and lipid or organisms, and concluded that the calcification was idiopathic introducing the term "idiopathic scrotal calcinosis." We have studied four cases of idiopathic scrotal calcinosis, one of which had scrotal calcinosis involving the whole of the scrotum. He presented with painless multiple nodules over the scrotum. He was subjected for surgery with SOS skin grafting, but as the scrotal skin is so lax, primary closure is easily possible. In all our four cases, primary closure was easily possible.
