Fig. 1. Composite images from one case demonstrating the various staining patterns of a primary pulmonary SCCA in an EBUS FNA. a Intermediate sized cell group with abundant eosinophilic cytoplasm without clear keratinization. HE stain, cell block. ×40. b p40 shows distinct nuclear labeling of most nuclei within the group. p40 IHC, cell block. ×60. c p63 shows distinct nuclear labeling of most nuclei within the group. p63 IHC, cell block. ×60. d CK5/6 shows strong cytoplasmic staining with negative images of the nuclei. CK5/6 IHC, cell block. ×60.
