A 42-year-old man with testicular tumor arising in the left undescended testis is reported. The patient had bilateral cryptorchidism and was admitted to our clinic on March 20, 1989, complaining of a mass in the lower abdomen. Colography indicated complete obstruction at the sigmoid colon, and computed tomography showed a larger mass in the lower abdomen and paraaortic lymph node swelling, as well as left hydronephrosis. We suspected that a testicular tumor had arisen in the undescended testis, and ileus was caused by the tumor mass. Since the patient was in a poor condition from preexisting ileus, chemotherapy consisting of cisplatin, bleomycin and vinblastine (PVB regimen) was immediately started without confirming the histology. After two courses of PVB regimen, bilateral orchiectomy, retroperitoneal lymphadenectomy, and left nephrectomy were performed. Pathological examination of the testis and resected lymph nodes revealed no residual tumor cells, and we could not identify the original histology. Additionally, two courses of chemotherapy were performed after surgery. The patient is well without evidence of disease one year and ten months after surgery.
