Cytologic Assessment of Endobronchial Ultrasound-guided Transbronchial Needle Aspirates in Sarcoidosis

Abstract

Liquid-based cytology and cell block specimens are equally important in maximizing the diagnostic yield in EBUS-guided and conventional TBNA in suspected sarcoidosis. Good interobserver agreement between cytopathologists was noted, with improved diagnostic yield after review by a pulmonary cytopathologist. None of the clinical factors assessed impacted on the diagnostic yield of the procedure on a per-node basis.
