This report deals with a case of malakoplakia of urinary bladder in a 68 year old female. The lesion of malakoplakia has been misdiagnosed as a neoplasm on several occasions in other institutes. This disease has been reported seldomly, and many urologists and pathologists alike have been unfamiliar to the lesion. An emphasis on the clinicopathologic features is made in order to prevent the serious misdiagnosis. The pertinent literatures are reviewed.

Malakoplakia is an extremely rare granulomatous disease caused by infection and known to occur mostly in immune-compromised hosts. The most common site of involvement is the bladder. Patients with malakoplakia of the bladder present with multiple intravesical masses and are often misdiagnosed with bladder cancer. As a result, appropriate treatment is delayed. Here we report a case of a patient with malakoplakia of the bladder that was misdiagnosed as bladder cancer.

Malakoplakia is a rare inflammatory disease which usually involves the lower urinary tracts, especially in immunocompromised patients. The characteristic feature is parenchymal infiltration by macrophages, known as von Hansemann cells, and intra- or extracytoplasmic Michaelis-Gutmann bodies. We report a case of renal malakoplakia in a renal allograft patient. Renal allograft biopsy was performed 1.5 years posttransplantation under the impression of chronic rejection. By light microscopy, inflammatory infiltrate composed of many macrophages and Michaelis-Gutmann bodies were present in the renal medulla and accompanied by moderate tubular atrophy and interstitial fibrosis.

Malakoplakia is a rare chronic inflammatory process, most commonly affecting the urinary tract. This entity was first described by Michaelis and Gutman in 1902. As of 1995, only 85 cases of malakoplakia of the gastrointestinal tract has been reported. The common sites of colonic involvement are the rectum, sigmoid, and right colon, in descending order of frequency. The most common disease associated with malakoplakia is colorectal carcinoma. Surgical resection is the treatement of choice for cases associated with carcinoma or complications. But in other cases, medical treatment could be attempted. Antimicrobial drugs, such as trimethoprime-sufamethoxazole, rifampin, or as recently suggested, ciprofloxacin can be used. We report a case of rectal malakoplakia treated by ciprofloxacin with a review of literatures.
