摘要

原發性支氣管內許旺細胞瘤是相對罕見的神經原性良性腫瘤。生長於氣管內可能導致咳嗽、咳血、呼吸困難與阻塞性肺炎。我們報告一位83歲男性同時存在原發性支氣管內許旺式細胞瘤與同側肺腺癌，並整理回顧支氣管內許旺式細胞瘤的相關文獻。就我們所知，文獻中未曾有與同側肺腺癌併存之支氣管內許旺細胞瘤的個案報告，而兩者之間的相關性依然未知。我們必須留意支氣管內良性腫瘤可能相似於氣管內轉移之惡性腫瘤的情形，因此針對支氣管內腫瘤進行軟式支氣管鏡切片是必要的，對於併存之癌症的分期、治療及預後有重要的影響。

Primary endobronchial schwannomas are relatively rare, benign tumors of neurogenic origin. Their presence within the bronchus may lead to cough, hemoptysis, dyspnea and obstructive pneumonia. We present the case of an 83-year-old man with a primary endobronchial schwannoma simultaneously occurring with an ipsilateral bronchogenic adenocarcinoma, and review the literature on primary endobronchial schwannomas. To date, primary endobronchial schwannomas coexisting with lung adenocarcinomas have not been reported, and their relationship is still unknown. We should always keep in mind that endobronchial benign tumors may mimic endobronchial involvement of malignancies. Bronchofiberscopic examination with biopsy is warranted for any endobronchial tumors, and will have an important influence on the staging, treatment, and outcome of coexisting cancers.
