Malakoplakia of the testis.

Two cases of malakoplakia of the testis are presented. Malakoplakia (soft plaque) is an uncommon chronic inflammatory condition of granulomatous type, the common denominator of which would appear to be an altered reactivity of macrophages. Its hallmark is the presence of Michaelis-Guttman bodies. Until the late 1950s, when a case involving the testis was described, the condition was thought to involve only the mucosae of the bladder, ureters, and renal pelvis. The most recent review of malakoplakia of the testis included only 10 known cases.
