Analysis of 2 cases of misdiagnosis of pulmonary bronchial adenoma
There were 2 cases of bronchial adenoma of the lung without any clinical symptoms.CT examination of the lung revealed 1 case of solid nodules and 1 case of ground glass nodules of the left lung,which were diagnosed as adenocarcinoma of the lung by imaging and freezing pathology.After completing relevant examinations,thoracoscopic wedges of the left lung were performed,and the postoperative pathology was all left lung bronchial adenoma.No special treatment was given after the operation,and the patients were followed up to about 4 years after the operation.The patients were in good condition with no signs of distant metastasis or recurrence of the tumor.Bronchial adenoma is a newly proposed benign tumor originating from the bronchial mucosal epithelium.It is usually found by chance in the surrounding pulmonary field during computed tomography.In the 5th edition of the World Health Organization's latest classification of thoracic tumors in 2021,a new BA/ciliated multinodular papilloma tumor(CMPT)is added and the tumor is clearly labeled as benign.The histological variation of bronchial adenoma can be divided into"classical"CMPT(proximal type)and"non-classical"CMPT(distal type).The typical pathological features are nodules in the lung parenchyma with clear boundaries,no envelope,papillary or alveolar adherent growth,consisting of continuous basal cell layer and/or ciliated cells,mucous cells,type Ⅱ alveolar epithelial cells,and alveolar surface cells.Due to the rare incidence of this tumor,few reports have been reported in China.Their clinical,radiological and pathological manifestations may mimic a variety of benign and malignant processes.The lack of understanding of clinicians makes it easy to be misdiagnosed as adenocarcinoma.2 misdiagnosed cases of bronchial adenoma in our hospital are reported as follows.
