摘要

肺部發炎性偽性腫瘤是一種罕見的原因不明的炎症反應。組織病理學的變化是由各種發炎細胞和間葉細胞浸潤造成，包括漿細胞、組織細胞、肥胖細胞、淋巴細胞以及梭狀間葉細胞。這篇報告描述一位62歲的女性病人，臨床表現咳血約三個月，胸部X光發現一個大的圓形腫瘤在右下肺葉，電腦斷層發現一個大小為8×5×5公分的腫瘤在右下肺葉，其中心呈低密度而周圍為不規則的厚壁。病人接受右下葉肺切除，病理組織檢查顯示為發炎性偽性腫瘤。由於台灣地區未有此病例報告，我們在此報告此病例之臨床表現、討論病理發現以及文獻的回顧。

Inflammatory pseudotumor of the lung is a rare and generally considered benign reactive inflammatory process of unknown etiology. It is composed of a variety of inflammatory and mesenchymal cells including plasma cells, histiocytes, mast cells, lymphocytes, and spindleshaped mesenchymal cells. This report refers to a 62-year-old female who suffered from hemoptysis for two months. Chest X-ray showed a big round soft tissue mass in the right lower lobe (RLL) of her lungs. Chest computed tomography revealed a 8×5×5 cm^3 space occupying lesion with central low density and peripheral irregular thick wall in the dependent portion of the RLL of her lungs. Under the impression of carcinoma of the lung, RLL lobectomy was performed. Pathological examination showed an inflammatory pseudotumor. To our best knowledge, this is the first case reported in Taiwan. In this study, we reported the clinical characteristics, discussed the pathological findings, and reviewed the literature concerning this rare pathological entity.
