[A case of retrovesical embryonal cell carcinoma].
We report a case of an extragonadal germ cell tumor in the retrovesical region. The patient complained of a perineal and micturition pain. Urethrography, CT and MRI showed a retrovesical tumor protruding into the bladder. Alfa-fetoprotein was increased to 12,170 ng/ml. Bilateral testes did not contain any palpable mass by careful palpation. No tumor was detected by ultrasonography, either. Clinically, he was diagnosed as having a retrovesical extragonadal germ cell tumor associated with paraaortic lymph-nodes and bilateral pulmonary metastases. Although he was treated by combination chemotherapy (PVB and VAB-6 regimen) and irradiation, he died of carcinomatosis about 6 months after the admission. There was no evidence of tumor in bilateral testes on autopsy. This case was a second case of extragonadal germ cell tumor originating from the retrovesical lesion in the literature.
