Intestinal metaplasia of the bladder, char- acterized by the presence of an intestinal-type epithelium in the urothelium, is a glandular proliferation and extremely rare benign le- sion.

Abstract
Intestinal metaplasia of the bladder, char- acterized by the presence of an intestinal-type epithelium in the urothelium, is a glandular proliferation and extremely rare benign le- sion. The pathogenesis of this uncommon entity is unclear, and its role as a precursor of adenocarcinoma is controversial. We pres- ent a case of a 45-year-old man admitted with macroscopic hematuria and mucosuria. Ul- trasound showed a 32×25×6 mm hypoechoic nodule with regular contours on the posterior wall. Histopathological examination following transurethral resection revealed an intestinal metaplasia against a background of cystitis glandularis.
