Idiopathic scrotal calcinosis

Idiopathic scrotal calcinosis, sometimes called dystrophic scrotal calcinosis, is a rare benign condition characterized by superficial calcifications within the skin of the scrotum of unclear etiology. The condition is primarily cosmetic but may recur following excision of the calcified bodies.


Idiopathic scrotal calcinosis typically affects men aged 20-40 years.


Proposed etiologies for idiopathic scrotal calcinosis includes epidermal inclusion cysts which calcify, necrosis and degeneration of the dartos muscle leading to dystrophic calcifications, and excessive discharge in eccrine epithelial cysts which leads to calcification of the debris build up in the lumina.
