中文摘要

無論從臨床或組織病理的觀點來看,膀胱發炎性假腫瘤屬於罕見之疾病。此病經過經尿道切除術後預後均很好。組織學上可發現梭狀細胞夾雜於黏液狀組織背景中,其間並有一些呈稀疏簇狀排列之部。另外尚有毛細血管增生及發炎細胞浸潤現象。免疫組織化學染色法可作為進一步確認之檢查,以和其他膀胱惡性腫瘤作一區別。然而臨床上重要之事為確認這種良性病灶以避免可能之誤診及不必要之過當治療。

英文摘要

A case of inflammatory pseudotumor (IPS) of the urinary bladder is described. Pseudotumor is rare, and may simulate a malignant tumor either clinically or histopathologically. The outcome is usually favorable after local excision, e.g. transurethral resection of the tumor. Histological examination showed spindle cells in a myxoid background with foci of a loose fascicular pattern, slight capillary proliferation, and inflammatory infiltrate. Immunohistochemical profile of IPS confirmed a myofibroblastic proliferation, and could differentiate IPS from other malignancies of the bladder. It is important to recognize this lesion as benign to avoid potential misdiagnosis and aggressive therapy.
