Idiopathic calcinosis of the scrotum--a specific entity of the scrotal skin. Case report.

A 69 year old patient with relapsing idiopathic scrotal calcinosis (ICS) is presented. Histological evaluation of the excised material showed the typical morphological features of calcified material within the corium. A review of the literature revealed 12 of 75 patients who had evidence of epithelial lining of the corial calcifications. Generally the calcified masses were surrounded by granulation tissue with mononuclear and foreign body giant cells. There is accumulating evidence for dystrophic calcification of cyst rather than an idiopathic genesis.
