Malakoplakia. Two unusual cases which presented diagnostic problems.
Two unusual cases of malakoplakia are presented. Both cases occurred outside the urinary tract (retroperitoneum and anus) and were diagnostic problems due to the paucity of Michaelis-Guttman bodies. One case mimicked a retroperitoneal malignant fibrous histiocytoma and the other a common perianal abcess.
