Primary Epithelial-Myoepithelial Carcinoma of the Lung Presenting as Multiple Synchronous Lesions

Primary epithelial-myoepithelial carcinoma of the lung is an extremely rare histologic form that originates in the bronchial glands. Pulmonary epithelial-myoepithelial carcinoma in the peripheral lung is extremely rare, and multiple primary pulmonary epithelial-myoepithelial carcinoma has not been reported to date. Here, we report a case of pulmonary epithelial-myoepithelial carcinoma presenting as multiple synchronous lesions. The patient underwent two treatments by video-assisted thoracic surgery within 3 years. At the 4-month follow-up, the patient had no evidence of recurrence. In conclusion, our case report may contribute to the understanding of pulmonary epithelial-myoepithelial carcinoma.
