Transitional cell carcinomas constitute 90% to 95% of urothelial tract cancers. Squamous cell cancers account for 3% to 7% of urothelial carcinomas and are more common in the renal pelvis and ureters.

The majority of primary carcinomas of the urinary bladder are urothelial cell carcinomas. Here, we report a patient who had a history of urothelial cell carcinoma of the bladder after neoadjuvant chemotherapy followed by radical cystectomy who subsequently developed poorly differentiated rectal adenocarcinoma with elevated plasma CEA (43.75 ng/mL) and CA19-9 (11,790 unit/mL) levels.
