精巣上体原発と考えられた平滑筋肉腫の1例

概要

A 63-year-old man presented with right scrotal swelling. A physical examination revealed a painless, palpable mass in the right scrotum. The mass was well defined and lobulated. Subsequently, a diagnosis of right epididymal tumor was made, and right high orchiectomy was performed. Hematoxylin-eosin and immunostaining revealed leiomyosarcoma of the epididymis. When a diagnosis of epididymal malignant tumor is made, the standard treatment is radical orchiectomy.
