Inguinal metastasis of a bladder mixed carcinoma with predominant adenocarcinoma component.

We report a case of urinary bladder mixed carcinoma with inguinal metastasis. Histological examination of the transurethral resection specimens revealed adenocarcinoma with small foci of squamous and transitional cell carcinomas. A right inguinal metastasis occurred 1 year after radical cystourethrectomy. Chemotherapy and radiotherapy were performed but the metastatic tumor remained unchanged.
