Abstract:
Cryptorchidism is a well-known and accepted risk factor for malignant germ cell tumors. Orchiopexy does not reduce the risk of testicular tumor. However, nonseminomas arising in the undescended testes are uncommon, and most of these tumors are in the advanced stage at diagnoses. In addition, an endodermal sinus tumor from an undescended testicle in adults has been reported to be quite rare. The management of these tumors is similar to the therapy for a testicular tumor in normally descended testis. Here we report a case of 27-year-old man who had a giant endodermal sinus tumor arising in the left intraabdominal undescended testis, which was successfully treated with an en bloc excision and EP (etoposide and cisplatin) chemotherapy. The patient has been free of recurrence for 15 months after surgery.
