Tracheal Lipoma-Case Report and Review of the Literature

原發性氣管內脂肪瘤是極少見的腫瘤，因為會造成類似阻塞性肺疾病的症狀，在診斷上是比較不容易的。我們病例報告了一位有氣管內脂肪瘤的病人，長期抱怨呼吸喘，但經治療後卻沒有明顯成效，在肺功能檢查的吐氣期間，發現吐氣流速為固定地減少，因此懷疑在氣管內有阻塞物的存在，電腦掃瞄在氣管中段發現了一個腫瘤，支氣管內視鏡證實腫瘤的存在，藉由支氣管鏡內雷射，腫瘤順利被切除。病理顯示為良性脂肪瘤，於手術後，病人呼吸喘的症狀改善許多。

Primary tracheal lipomas are extremely rare neoplasms and can be difficult to diagnose due to their capacity to mimic other obstructive lung diseases. We report the case of a male patient with tracheal lipoma. He complained of shortness of breath for a long time with little response to treatment. During forced expiration in the pulmonary function test, a dramatic constant reduction in expiratory flow of the flow-volume curve was noted. Based on that, an obstructing lesion in the airway was suspected. A computed tomographic scan revealed the presence of a tumor in the mid-trachea. The tumor was confirmed by fiberoptic bronchoscopy and successfully resected by endoscopic laser. Histologic examination of the tumor showed a benign lipoma. After surgical treatment, the patient reported significant improvement in his shortness of breath.
