Pulmonary Adenofibroma: A Rare Presentation of a Benign Lung Nodule-A Case Report

肺腺纖維瘤是一種非常罕見的良性間葉細胞瘤，在目前的文獻資料庫裡只有極少數的臨床病例報告。不常見的肺部腫瘤由各種不同組織型態的細胞所構成，也會有不同的影像學表徵以及臨床表現。我們報導了一位六十歲男性以輕微發燒及全身倦怠就診，初步理學檢查及配合實驗室和影像學診斷為急性肝炎及右側肋膜積液，肋膜積液抽吸檢查顯示淋巴細胞為主的滲出液；進一步安排胸部電腦斷層檢查發現右上肺一個邊緣清楚的結節。經手術取得檢體冰凍切片初步報告為中度分化的肺腺癌，然而最終病理報告修正為良性腫瘤。藉由此病例報告讓臨床醫師增加對此良性肺腫瘤的了解。

Pulmonary adenofibroma is a rare primary benign mesenchymal lung tumor that has been seldom reported in the currently available literature. Unusual lung tumors constitute a broad range of histological types that unsurprisingly have a wide spectrum of imaging appearances and clinical presentations. Herein, we report a 60-year-old male who complained of low-grade fever and general malaise, and was tentatively diagnosed as having acute hepatitis and pleural effusion, accompanied with the incidental finding of pulmonary nodule on chest computed tomography (CT), which was ultimately diagnosed as pulmonary adenofibroma. The initially challenging frozen section reading raised the suspicion of malignancy, but ultimately the diagnosis was revised to benign pulmonary adenofibroma. This case can increase our awareness of this extremely rare benign lesion in the future.
