陳旧性陰嚢内血瘤の1例

Abstract

尿閉, 右陰嚢内の無痛性腫瘤を主訴とした94歳男で, 会陰外傷の病歴はなく, 腫瘍マーカーは正常範囲内であった.透光性はなかった.精巣癌の診断で, 右高位精巣摘除術を行った.腫瘤と正常な右精巣との境界は明瞭であった.組織学的に慢性血瘤に特徴的なコレステリン結晶の沈着が認められ, 総鞘膜内に発生した陳旧性陰嚢内血瘤と考えられた

We report a case of chronic scrotal hematocele. A 94-year-old man complained of urine retention and a painless mass in the right scrotum. He had no history of trauma at the perinium. Tumor markers such as human chorionic gonadotropin, alpha fetoprotein and carcinoembryonic antigen were within normal limits. A transillumination test was negative. A right high orchiectomy was carried out after admission with the diagnosis of suspicion testicular cancer. The extracted mass measured 85 x 60 x 75 mm and contained old brownish black blood. The right testis was located separately from the mass and had a normal appearance. Microscopic examination revealed depositions of cholesterin crystals characteristic of chronic hematocele.
