Malacoplakia of the bladder: a case report of resolution with bethanechol, trimethoprim-sulfamethoxazole and ascorbic acid.

Malacoplakia is a granulomatous disease that most frequently involves the urinary tract but also may involve the genital tract, gastrointestinal tract and retroperitoneum. It is believed to be infectious in origin, secondary to a deficiency of intracellular lysosomal digestion, and heretofore considered a chronic problem. We report a case of malacoplakia of the bladder, which was treated successfully with a combination of bethanechol, trimethoprim-sulfamethoxazole and ascorbic acid.
