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 an uncommon granulomatous disease most frequently found in the bladder or ureter. Howevcr, it has been reyorted in almost every ather organ and structure, the colon is the most common site of malakoplakia outside the urogenital tract and colonic carcinoma is the most commonly associated disease. A case of malakoplakia of the colon in a 54-year-old female is reported. Sigmoidoscopy revealed multiple whiteyellowish nodules simulating polypoid lesion at 10cm from the anal verge. The biopsy showed characteristically comprised submucosal proliferations of histiocyte and chronic inflammatory cells with typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Intravenous pyelogram showed no evidence of involvement of the urinary system. These nodules were removed by endoscopic polypectomy, So far, this is the first case of isolated colonic malakoplakia in Korea.
