title: [Annular constriction of the rectum secondary to urothelial carcinoma of the bladder].
abstract: Recurrent urothelial carcinoma of the bladder is often a locally progressive disease. Invasive bladder cancers frequently show lymphatic or hematogenous metastasis. Regional lymph node metastasis is a frequent finding and may be the first sign of recurrence. Rectal involvement and obstruction is rare, but metastasis to the colon, small intestine, and stomach have been reported. Here, we report an unusual case of urothelial carcinoma of the bladder manifesting as an annular rectal obstruction.
