[A case of metastatic urinary bladder tumor from colon carcinoma].
A 62-year-old female patient underwent an operation for a brain tumor. The pathological diagnosis of the resected specimen was metastatic adenocarcinoma with signet-ring cells. The primary lesion was found in the ascending colon. In addition, a non-papillary and pedunculated tumor was found on the right wall of the bladder on cystoscopy. Biopsy of the bladder tumor showed adenocarcinoma with signet-ring cells, which was the same as the histologies of the colon and the brain tumors. Under the diagnosis of metastatic bladder tumor, transurethral resection of the tumor was performed. This is the first case of metastatic bladder carcinoma from the colon reported in Japan.
