Primary choriocarcinoma of the urinary bladder.
We report a case of choriocarcinoma of the bladder. The initial biopsy of the bladder tumor showed co-existence of choriocarcinoma and transitional cell carcinoma, while the cystectomized bladder tumor and metastatic tumors were composed only of choriocarcinoma. The diagnosis of choriocarcinoma was confirmed morphologically and by the demonstration of hCG in the tumor and in the serum.
