肺黏液表皮样癌肺内转移1例并文献复习

Intrapulmonary Metastasis of Mucoepidermoid Carcinoma of Lung:Case Report and Literature Review

目的:分析肺黏液表皮样癌(Pulmonary mucoepidermoldcarcinoma,PMEC)的临床特征和诊断方法,提高对该病的认识,以期做到早发现、早诊断、早治疗、改善患者预后。方法:回顾性分析1例大理大学第一附属医院确诊的合并肺内转移的PMEC患者的临床资料,分析其临床特点及诊断方法。结果:患者无特殊临床表现,经病理确诊为PMEC。结论:PMEC是一种罕见的肺部恶性肿瘤,其发病年龄广,发病率低,发病机制可能与MAML2基因融合或重排有关。临床表现和影像学表现缺乏特异性,诊断主要依靠病理和免疫组化相结合。

Objective:To analyze the clinical characteristics and diagnostic methods of Pulmonary mucoepidermoldcarcinoma(PMEC),and to improve the understanding of this disease,so as to achieve early detection,early diagnosis,early treatment and improve the prognosis of patients.Methods:The clinical data of 1 case of PMEC with intrapulmonary metastasis diagnosed in the First Affliated Hospital of Dali University were retrospectively analyzed,and its clinical characteristics and diagnostic methods were analyzed.Results:The patient had no special clinical manifestations and was diagnosed as PMEC by pathology.Conclusion:PMEC is a rare pulmonary malignant tumor with a wide age and low incidence,and its pathogenesis may be related to the fusion or rearangement of MAML2 gene.The clinical and imaging manifestations lacked specificity,and the diagnosis mainly depended on the combination of pathology and immunohistochemistry.
