Metastatic Leydig cell carcinomas account for less than 0.2% of all testicular cancers, and may be associated with sex hormone production. Leydig cell carcinoma is relatively refractory to radiotherapy and chemotherapy, and median survival of patients with metastatic disease is less than 2 years. Presented are three cases of metastatic Leydig cell cancer, and a review of the literature pertaining to this rare tumor.
