title: [A case of chronic scrotal hematocele].
abstract: 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.
