Pedunculated malacoplakia: A case report

A 52-year-old woman was admitted to our hospital with the chief complaint of asymptomatic macrohematuria. On cystoscopy, the tumor in the bladder was covered with normal mucosa which looked like inverted papilloma. E. coli was cultured from her urine. She was treated with endoscopic and medical therapies. Histologically, there were large mononuclear hystiocytes known as Von Hansemann cells and small intracellular and extracellular calculospherules called Michaelis Gutmann bodies. The pathological diagnosis was malacoplakia. The patient has remained free of disease for 12 months postoperatively.
