Malakoplakia is a rare chronic inflammatory disease that was originally described in the urinary bladder but can involve many other organs and soft tissues. It is believed to be caused by an alteration in the bacterial phagocytic system. Clinically, it is described as single or multiple tumors that can appear in any part of the body. Histologically, the presence of Michaelis-Gutmann bodies is pathognomonic. Malakoplakia in children is rare. Few pediatric cases in the urinary tract, kidney, or gastrointestinal tract have been published. We present a case of urinary and gastrointestinal malakoplakia in a 12-year-old girl.
