Seven cases of testicular tumors with two cryptorchidism.

Seven patients with testicular tumor were reviewed. Among them were two patients with cryptorchidism which had not been suspected. All were treated with orchidectomy through an inguinal incision or by laparotomy. Afterwards the seminomata underwent radiation therapy, and in the malignant teratoma intermediate, when ever possible, a retroperitoneal lymphnode dissection was done. The malignant teratoma undifferentiated (stage IV) received chemotherapy (cis-diamminodichloroplatinum) with good results. The lymphoblastic sarcoma (stage IV) was treated with methotrexate and vincristine. It is suggested that in patients with cryptorchidism the undescended or intra-abdominal testis should always be explored, and excised if suspect or underdeveloped.
