[A case report of malignant fibrous histiocytoma of the scrotal wall. A statistical study of 56 cases of primary tumors of the scrotal wall in Japanese literature].

The case was a 72-year-old male who had the chief complaint of a painless, gradually enlarging tumor in his left scrotum for the past 6 months. Radical orchiectomy was performed. Histologic examination of the tumor revealed a malignant fibrous histiocytoma of the scrotal wall. He received chemotherapy with Vincristine and Cyclophosphamide but no radiation therapy. He is living without metastasis during the 4 months after the operation. We proposed a new classification of intra scrotal tumors according to the site of origin. Including our case, 56 cases of primary tumors of the scrotal wall have been reported in the Japanese literature. The diagnostic, therapeutic and prognostic problems were discussed.
