Tracheal and Bronchial Respiratory Epithelium
Normal bronchial respiratory epithelium usually appears as monolayer tissue fragments and strips in bronchoscopic brush, lavage, aspirate, or transbronchial/tracheal fine needle aspirations. Epithelial cells have a uniform, honeycomb appearance en face, and columnar shape with basally located round uniform nuclei, terminal plates and cilia from profile (Fig. 2.1A, B & C). Rare goblet cells (Fig. 2.2) and reserve cells (Fig. 2.3) can be present; they are more frequently found in reactive conditions (see Chapter 3).
