Intestinal metaplasia of the bladder: A rare case report

Abstract

Intestinal metaplasia of the bladder, characterized by the presence of an intestinal-type epithelium in the urothelium, is a glandular proliferation and extremely rare benign lesion. The pathogenesis of this uncommon entity is unclear, and its role as a precursor of adenocarcinoma is controversial. We present a case of a 45-year-old man admitted with macroscopic hematuria and mucosuria. Ultrasound 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.
