IntroductionEndobronchial ultrasound-guided fine-needle aspiration biopsy (EBUS-FNAB) is a minimally invasive method used to obtain cytological or histological specimens of masses and lymphadenopathies (LAP) adjacent to the trachea and bronchi. Granulomas, which represent a chronic inflammatory response and occur for a variety of reasons, like a 'sarcoid-like reaction', cause LAPs. In this study, it was aimed to evaluate the long-term follow-up results of granulomatous lymphadenitis diagnosed with EBUS-FNAB and to investigate whether granulomatous lymphadenopathies were precursors of malignancies that occurred during the follow-up period. Material and methodsThe medical records of 123 patients who underwent EBUS-FNAB and were diagnosed with granulomatous lymphadenitis were retrospectively reviewed. Age, gender, acid-fast bacilli (ARB) staining, tuberculosis culture and tuberculosis polymerase chain reaction (PCR) culture results were examined by FNAB, and the procedure indications of all patients diagnosed with granulomatous lymphadenitis were recorded. The longterm health records of 52 patients could not be accessed. Data were collected from 71 patients. The progression, regression or stable conditions of LAPs in the long-term radiological follow-up of at least two years and the treatment conditions of diagnosis after biopsy were examined.
