Three cases of pulmonary leiomyosarcoma were presented. The characteristic clinical features were described with review of literature. In comparison with bronchogenic carcinoma, the leiomyosarcoma has some characteristics: 1) On chest X-ray, it usually appears as a sharply demarcated, even density round mass, growing rapidly within the lung, it rarely accompanies with hilar or mediastinal lymph node metastasis. 2) The preoperative cytological or pathological diagnosis is difficult either by sputum smear or by bronchoscopic biopsy or by fine needle percutaneous aspiration biopsy. 3) Pathological differential diagnosis of leiomyosarcoma of lung from anaplastic lung cancer is difficult. In conclusion, the primary pulmonary leiomyosarcoma is a rare malignant tumor, detecting the present illness seriously, paying attention to the chest X-ray films characterize, early surgical resection is the only way to get diagnosis and effective treatment method.
本文报告了3例肺平滑肌肉瘤病例。结合文献复习描述了其特征性临床特点。与支气管肺癌相比，平滑肌肉瘤具有一些特点：1）胸部X线检查时，通常表现为边界清晰、密度均匀的圆形肿块，在肺内生长迅速，很少伴有肺门或纵隔淋巴结转移。2）术前通过痰涂片、支气管镜活检或经皮细针穿刺活检进行细胞学或病理诊断均困难。3）肺平滑肌肉瘤与未分化肺癌的病理鉴别诊断困难。总之，原发性肺平滑肌肉瘤是一种罕见的恶性肿瘤，重视本病，注意胸部X线片特征，早期手术切除是获得诊断及有效治疗的唯一方法。
