Abstract

The clinical data for a patient with primary lung adenocarcinoma complicated with pulmonary hamartoma, who admitted to Zunyi Medical University Hospital in September 2020, was retrospectively analyzed. The 62-years-old male visited outpatient service because of dysphagia in March 2015, and the pulmonary nodules were found. In September 2020, the computed tomography indicated the enlarged nodule in the lower lobe of left lung with lobulation, and there was ground glass nodule in the upper lobe of left lung. After thoracoscopic wedge surgery, the primary pulmonary adenocarcinoma in the upper lobe of left lung and pulmonary hamartoma in the lower lobe of left lung were confirmed by pathology. Whole exon sequencing revealed that kinesin family member 20B () gene was not expressed in lung adenocarcinoma, but was expressed in pulmonary hamartoma. The clinical manifestations of lung adenocarcinoma complicated with pulmonary hamartoma was not typical, which could locate in the same side and different sides of the lung. The imaging manifestations of the 2 kinds of tumors were diverse and can not be completely distinguished. The pathological examination after surgery is the gold standard, and the possibility of malignant transformation of pulmonary hamartoma should be warned.
