Figure 4: Immunohistochemical analyses of the left 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 staining, ×200. (b) Ciliated columnar cells, mucin-containing lining cells, and mucous lakes by H and E, ×400. (c) The basal cell layer was highlighted by p40 immunostaining, ×200. (d) Cytoplasmic stain was also positive in three components by BRAF V600E, ×200
