悪性精巣Leydig 細胞腫の1例

Abstract

A 69-year-old Japanese man was referred to our hospital for a left inguinal testicular tumor and paraaortic lymph node swelling and pleural dissemination. A left orchiectomy was performed in October 2013. Histologically, this testicular tumor was a malignant Leydig cell tumor. The antineoplastic agent mitotan was administered after the orchiectomy. Two months later, although his plasma level of testosterone had de-escalated, the para-aortic lymph node did not decrease in size. A retroperitoneal lymph node dissection was performed in January 2014. Unfortunately, three days after the surgery, the patient died due to disseminated intravascular coagulation and gastrointestinal hemorrhage of unknown cause.
