Idiopathic calcinosis of the scrotum consists of multiple asymptomatic nodules of the scrotum without any underlying disease. We presented a case of idiopathic calcinosis of the scrotum and compared it with other reported cases in Korea, A 47-year-old farmer had slowly growing, asymptomatic, hard scrotal nodules which were 1cm in diameter and 6 in number for about twenty years. KUB X-ray film showed two radiopaque densities on the scrotal area. Histopathological finding revealed amorphous, basaphilic masses with acicular clefts which were confirmed as calcification in Von Kossa stain and surrounding foreign body granulomatous inflammatory reaction.
