title: [A case of seminoma in an intra-abdominal cryptorchidism associated with ipsilateral renal agenesis].
abstract: We encountered a case of seminoma arising from an intra-abdominal cryptorchidism associated with ipsilateral renal agenesis. A 42-year-old male patient was referred to this hospital with a complaint of right upper abdominal distention with pain. Radiologic examination demonstrated a right retroperitoneal mass, 12 cm in diameter, while the ipsilateral kidney was not detectable. Intra-aortocaval lymphnodes were swollen at the renal hilus level. The patient underwent tumor resection and lymphadenectomy. A histopathological diagnosis of seminoma with para-aortic lymphnode involvement was made. A definite diagnosis was seminoma (pT1 pN3M0) arising from cryptorchidism associated with right renal agenesis. The present case is the third of its kind reported in the literature.
