Malakoplakia in urology: six cases report and review of the literature

Malakoplakia (MLP) is a rare chronic granulomatous disease that is believed to happen because of an alteration in the bacterial phagocytic system. This entity is characterized by one or multiple tumorations that can appear in any part of the body leading to it's misdiagnosing as a malignant condition. The genitourinary tract is frequently involved. Pathologic study of these lesions shows tissue infiltrated by inflammatory cells (macrophages and hystiocites) with intracytoplasmatic inclusions, which are known as Michaelis-Gutmann bodies. Usually is a benign condition self-limited and is associated with recurrent urinary tract infection (UTI), this condition has a good response to prolonged treatment with fluoroquinolones. We will report six cases that were diagnosed and treatment in our institution during an eight year period. We report still a review of the available literature.
