Malakoplakia is a rare lesion of granulomatous inflammation which mainly affects urinary bladder but may involve other parts of the body. Differentiation from neoplastic process is often difficult due to its tumorous gross appearance and similarity to carcinoma microscopically. Malakoplakia of the prostate is even rare. We present a case of prostatic malakoplakia masquerading as a rectal tumor due to formation of a fistulous tract to the rectal muscular layers accompanied with ulceration of the rectal mucosa. Its clinical course is different from those of most reported cases, while the outcome is as satisfactory as in usual cases.
软斑病是一种罕见的肉芽肿性炎症病变，主要累及膀胱，但也可能累及身体其他部位。由于其肿瘤样大体外观以及在显微镜下与癌相似，因此常常难以与肿瘤性病变相鉴别。前列腺软斑病更为罕见。我们报告一例前列腺软斑病，因其形成通向直肠肌层的瘘管并伴有直肠黏膜溃疡，而伪装成直肠肿瘤。其临床病程与大多数报道的病例不同，但其结局与通常情况一样令人满意。
