Abstract

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used for diagnosing intrathoracic lymphadenopathy. Here, we present two cases of endobronchial polyp formation after an EBUS-TBNA for suspicious malignant lymph nodes. An inflammatory polyp should be considered as a possible differential diagnosis for a newly developed mass after an EBUS-TBNA.

Keywords: Endoscopic ultrasound guided needle aspiration; implantation; metastasis; tumor.
