肺部漿細胞肉芽腫,發病原因仍不清楚,大都認爲是炎症後所形成肉芽腫。除了少數病例因咳嗽、發燒及體重減輕外,大都爲無症狀而於X光檢查中,意外發現肺部腫瘤而就醫。病理檢查,腫瘤主要由漿細胞、泡狀組織球,淋巴球及纖維基質構成的肉芽腫。治療爲外科切除,預後不錯。本篇報告一例十歲病童因乾咳一年半之久,最近因臉色蒼白及體重減輕就醫,胸部X光及電腦斷層檢查發現左肺呈一巨大腫瘤,經病理切片檢查,證實為漿細胞肉芽腫。因個例少見,特提出報告,並參考文獻加以討論。
Pulmonary plasma cell granuloma is very rare in pediatric field. Most of them are asymptomatic, and are usually found to have lung tumor accidentally by chest X-ray cxamation. The granuloma is characterized by the proliferation of plasma cells along with other mesenchymal elements. We report a case of 10-year-old boy who suffered from dry cough, pale face and body weight loss for a longtime. Chest X-ray and CT scan revealed a lung tumor which was proved to be plasma cell granuloma after wedge biopsy. He was regularly followed up at OPD with stationary status. He may receive surgical resection in future.
