Figure 2: Immunohistochemical analyses of the right lower lobe ciliated muconodular papillary tumor. (a) The ciliated muconodular papillary tumor was composed of ciliated columnar cells, mucous cells, and basal cells by H and E, ×200. (b) Cuboidal to low columnar cells with cilia, mucin-containing lining cells, and mucous lakes by H and E, ×400. (c) Most lining mucous cells have a basal cell layer, which is highlighted by p40 immunostaining, ×200. (d) Cytoplasmic staining was positive in three components of ciliated columnar cells, mucous cells, and basal cells by BRAF V600E, ×200
