Needle biopsy of enlarged lymph nodes is an accepted method for the diagnostic workup of sarcoidosis, but the optimal endosonography‑guided approach is yet to be determined. The aim of our study was to assess the relative diagnostic yield of combined ultrasound‑guided needle aspiration (CUS‑b‑NA), which includes endobronchial ultrasound‑guided transbronchial needle aspiration (EBUS‑TBNA) with endoscopic ultrasound fine‑needle aspiration (EUS‑b‑FNA), as well as the role of the cell block (C technique and lymph node localization in the diagnos
