目的 :探讨细支气管肺泡细胞癌的临床特征及误诊原因。方法 :回顾分析我院 1992年 1月～ 2 0 0 2年 5月误诊的 16例细支气管肺泡细胞癌病例的临床资料。结果 :细支气管肺泡细胞癌首发症状以咳嗽、进行性呼吸困难及咯血为多见。结节型细支气管肺泡细胞癌易与结核球和炎性假瘤误诊 ,浸润型和弥漫型细支气管肺泡细胞癌易与肺部感染、浸润型肺结核和血行播散型肺结核等误诊。结论 :细支气管肺泡细胞癌临床及X线表现多样 ,易误诊误治。经支气管镜肺活检和早期开胸探查分别是诊断浸润型或弥漫型细支气管肺泡细胞癌和孤立结节型细支气管肺泡细胞癌的可靠方法
Objective: To investigate the clinical characteristics and misdiagnosis of bronchioloalveolar cell carcinoma. Methods: A retrospective analysis of our hospital from January 1992 to May 2002 misdiagnosed 16 cases of bronchioloalveolar cell carcinoma of the clinical data. Results: The first symptom of bronchioloalveolar cell carcinoma was cough, progressive dyspnea and hemoptysis. Nodular bronchioloalveolar cell carcinoma is easily misdiagnosed with tuberculoma and inflammatory pseudotumor, infiltrative and diffuse bronchioloalveolar cell carcinoma with pulmonary infection, infiltrative pulmonary tuberculosis and hematogenous disseminated pulmonary tuberculosis. Conclusion: Bronchial alveolar cell carcinoma has various clinical and X-ray manifestations, and is easily misdiagnosed and mistaken. Bronchoscopic lung biopsy and early thoracotomy are reliable methods for the diagnosis of infiltrative or diffuse type bronchioloalveolar cell carcinoma and isolated nodular bronchioloalveolar cell carcinoma
