A 75-year-old man visited our clinic on November 11, 1982 with the complaint of a painless mass in the right scrotum. The mass was hen's egg sized and hard. Surgery was performed under the diagnosis of testicular tumor. Right hemiscrotectomy with right inguinal orchiectomy was performed because of a scrotal skin invasion of the tumor. The spermatic cord, testis and epididymis were grossly normal. The tumor was located just beneath the testis, and it was considered to be scrotal tunicus in origin. The tumor was elastic and hard, and the cut surface showed a yellowish white and lobulated appearance. The histological diagnosis was malignant fibrous histiocytoma. Postoperatively, radiotherapy for a total dosage of 4,910 rads was given. The patient is alive and well without any sign of recurrence 19 months after operation. The 20 cases reported in Europe, America and Japan, including our case, were tabulated and some discussion is made.
