Figure 1 A representative image of ciliated muconodular papillary tumors with hematoxylin–eosin staining. The epithelial components of the lesions consisted of a mixture of ciliated columnar cells (arrow), mucous cells (asterisk), and basal cells (arrowhead).

Figure 3 Immunohistochemical analyses of the BRAF-V600E ciliated muconodular papillary tumors. Each of the three epithelial components (i.e., ciliated columnar cells, mucous cells, and basal cells) exhibited cytoplasmic staining for BRAF-V600E. The monoclonal antibody also strongly cross-reacted with the cilia of the columnar cells (the internal positive control).
