Genito-urinary malacoplakia. Report of 10 cases and review of the literature

The malakoplakia is a rare and benign disease. Its urinary localisation is commonly known. It has no clinical particularity. The diagnosis is histological. The physiopathology is infectious associated with a local macrophage function failure. The treatment associates antibiotic and colinergic drugs. Surgical removal is necessary only when the organ is destroyed. We report 10 cases of urinary malakoplakia with 4 renal localisation's causing pyonephrosis in the majority of cases, 3 prostatic localisation's that were wrongly considered as prostatic adénocarcinoma after a rectal examination and finally 3 testicular localisation's causing a necrotic destruction of the testis. The urinalysis was positive in 4 cases. We did 4 kidney removals, 3 endoscopic prostatic resections and 3 testis removals. The diagnosis was made by the histological examination of the surgical products.
