肺部平滑肌瘤5例报告并文献复习

Leiomyomas of the lung:report of 5 cases with literature review

本文收集国内有关文献报告的肺部平滑肌瘤２２例及我院的５例共２７例进行分析，肿瘤位于气管支气管１８例；肺实质９例，其中发生于肺血管的２例。４０岁以下占７０．４％。主要表现为咳嗽、胸痛、咯血、发热、反复发作性肺炎及大气道阻塞性呼吸困难。临床上易误诊为腺瘤、结核球及肺癌。胸部Ｘ线检查难以确诊，纤维支气管镜活检对诊断很有帮助。保守性肿瘤局限切除，预后同样良好。Ｎａ－ＹＡＧ激光治疗是一种有效的方法。

cases with leiomyoma of the lung, previously reported 22 cases in the literatures and 5 cases in our hospital, were reported. The tumors located in tracheobronchial trees in 18 patients and in the peripheral lung field in 9 patients. Two of them were found to be in the pulmonary vessels. 70.4% of the patients were under 40 years of age. The main clinical manifestations were cough, chest pain, hemoptysis, fever, repeated pneumonitis and dyspenea due to obstruction of the main airway. This disease was usually misdiagnosed as adenoma, tuberculoma or lung cancer. It is diffecult to make a correct diagnosis only by chest X ray examination. Fiberoptic bronchoscopic biopsy is helpful to it. Conservative surgery may be a good choice of therapy. Nd YAG laser resection is effective for broncheal leiomyoma.
