Usefulness of endobronchial ultrasound-guided transbronchial needle aspiration in distinguishing sarcoidosis from recurrent cancer in patients with lymphadenopathy after surgery.
Endobronchial ultrasound-guided transbronchial needle aspiration is a new minimally invasive test for investigating mediastinal and hilar lymphadenopathy. It is sometimes difficult to distinguish between a recurrent malignant lymph node and lymphadenopathy due to sarcoidosis in patients who develop lymphadenopathy after surgery for a malignant tumor. ⋯ Endobronchial ultrasound-guided transbronchial needle aspiration might be useful in differentiating between benign lymphadenopathy, including sarcoidosis, and cancer recurrence in patients with mediastinal or hilar lymphadenopathy after surgical resection of a malignant tumor.
