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.

Malacoplakia is an uncommon granulomatous inflammatory disease, which predomina- ntly affected the urinary tract, particularly the urinary bladder. The prostatic involve- ment of malacoplakia is extremely rare and may clinically mimic prostate cancer. A correct diagnosis of malacoplakia can be made by histopathologic findings characterized by accumulations of macrophages containing typical intracytoplasmic inclusions(Michael is-Gutmann bodies). We report a case of prostatic malacoplakia, which was incidentally found in prostate biopsy performed to confirm clinically suspected prostate cancer.

A case of malacoplakia of the prostatic gland associated with prostatic nodular hyperplasia from a 69 years old man was presented, and its light and electron microscopic and immunohistochemical features were discussed along with its pathogenesis. This lesion was incidentally found in a transurethral prostatectomy specimen, and consisted of large number of epithelioid cells in which were typical cytoplasmic inclusions known as Michaelis-Gutmann bodies. Ultrastructurally, these inclusions showed a dense, central calcified bodies of various developmental stages. Immunohistochemical study using antilysosomal antibody revealed no lysosomal activity. Based on these findings, we could suspect that main problem for this development of malacoplakia is altered intracellular digestion process of foreign biologic materials.
