A Case of Retroperitoneal Extragonadal Germ Cell Tumor with Cryptorchidism / 대한비뇨기과학회지

ABSTRACT

We experienced one case of extragonadal germ cell tumor of retroperitoneal origin. The patient had orchiopexy of left cryptorchidism twenty years ago. The left testis was atrophied and the right testis was normal on palpation. Retroperitoneal exploratory surgery and complete excision of the mass were performed. The pathologic report identified seminoma. There was no evidence of metastasis computed tomography and bone scan. Then left orchiectomy and right testicular biopsy were performed. The left testis demonstrated hyalinization of seminiferous tubules and right testis demonstrated normal finding, but both specimens showed no malignancy or carcinoma in situ. The patient was treated with BEP(bleomycin, etoposide, cisplatin) combination chemotherapy. With a follow-up of 24 months the patient remains disease free.
