慢性に経過した陰嚢内血瘤の1例

Abstract

A 60-year-old man visited our hospital because of a painless swelling of the left scrotal content which enlarged gradually for these five years. He had no history of trauma at the perineum. Tumor markers such as HCG, AFP and CEA were within normal limits. Left high orchiectomy was carried out after the admission under the diagnosis of suspicious testicular cancer. The resected mass, 16.5 x 12.5 x 9.5 cm in diameter and 900 g in weight, was encapsulated within the tunica vaginalis by a fibrous membrane and contained about 300 ml of reddish black liquid. The normally-appearing left testis was located separately from the mass. Microscopic examination revealed depositions of cholesterine crista in the wall, which are characteristic for a chronic hematocele.
