ABSTRACT
Thymic epithelial tumors are relatively rare. We report two cases of thymoma and thymic carcinoma diagnosed by bronchoscopy. In Case 1, an endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed at the left lower trunk for a mediastinal tumor invading the pericardium. The patient was diagnosed with thymoma. In Case 2, EBUS-TBNA was performed of a posterior mediastinal tumor located between the tracheal carina and spine. The patient was diagnosed with thymic carcinoma. Thymic epithelial tumors are often located in the anterior mediastinum, and there are few reports of bronchoscopic diagnosis. EBUS-TBNA was considered to be useful in the diagnosis of thymic epithelial tumors in contact with the central airway.
