　59歳，男性．主訴は15年来の陰嚢の無痛性多発性腫瘤であった．特徴的な局所所見から特発性陰嚢石灰沈着症と診断し，手術的に切除した1例を報告した．特発性陰嚢石灰沈着症においてカルシウム代謝について検討している報告はあまりみられない．そこで本症例において，カルシウム代謝に関する諸検査を施行した．血清カルシウムとリンの値は正常であった．また，イオン化カルシウム，25（OH）ビタミンD,1.25（OH）₂ビタミンD，カルシトニンそれに上皮小体ホルモンは基準値範囲内であり，明らかなカルシウム代謝異常を示唆する所見は得られなかった．

A 59-year-old man who had a chief complaint of asymptomatic multiple nodules in the scrotum which were first noted at the age of fourty-four. Since then, the nodules had gradually increased in size and number but the patient had never had any associated complaints. The nodules were firm, nontender, varying in size and containing yellowish material in their center. Diagnosis of idiopathic calcinosis of the scrotum was made and all visible nodules were surgically removed. The serum levels of calcium, phosphate, uric acid and calcium ion were normal. The serum levels of 25-OH vitamin D and 1.25 (OH)₂ vitamin D were also normal.
