目的 报道肺部少见的其他原发性恶性肿瘤。方法 收集上海市胸科医院 1985～ 1996年切肺手术证实的 2 1例肺部少见原发性恶性肿瘤进行临床分析。结果 全组术前均未确诊 ,部分病例甚至需借助特殊染色或免疫组化检查得以确诊。其中肺恶性淋巴瘤 8例 ,平滑肌肉瘤 4例 ,纤维肉瘤 4例 ,血管内皮细胞瘤 3例 ,恶性神经鞘瘤和癌肉瘤各 1例。结论 对少见的肺部原发性恶性肿瘤术前诊断较困难 ,部分病例须在切除后借助特殊病理检查才能确诊 ,唯一的治疗方法是早期手术切除。
Objective To report other rare primary lung cancer. Methods Twenty-one cases of rare primary malignant lung tumors, which were confirmed by the thoracic surgery in Shanghai Chest Hospital from 1985 to 1996, were collected for clinical analysis. Results The whole group were not diagnosed preoperatively, and some cases even need to be diagnosed by special staining or immunohistochemistry. Among them, 8 cases of pulmonary malignant lymphoma, 4 cases of leiomyosarcoma, 4 cases of fibrosarcoma, 3 cases of vascular endothelial cell tumor, 1 case of malignant schwannoma and 1 case of carcinosarcoma. Conclusions Preoperative diagnosis of rare primary lung cancer is more difficult. Some cases should be confirmed by special pathological examination after resection. The only treatment is early surgical resection.
