Proc (Bayl Univ Med Cent). 2020 May 18;33(3):389-390. doi: 10.1080/08998280.2020.1764317. eCollection 2020 Jul.


Malakoplakia is a rare chronic granulomatous disease with potential to affect multiple organs. Gastrointestinal involvement is considered one of the most common locations outside of the urinary tract. Herein, we present the case of a man who presented to our clinic with painless hematochezia. Physical examination findings were unremarkable; however, colonoscopy revealed a frond-like/villous, fungating, and polypoid nonobstructing circumferential mass in the rectum. Histopathological examination of the lesion revealed findings consistent with malakoplakia.

Keywords: Colon; Michealis-Gutman bodies; colonoscopy; macrophages; malakoplakia.
