TP63 and neoplasm: In these rare doubtful cases of ‘scattered’ versus ‘rim‐like’ staining, the potential that these cells represent ΔNp63/p40+ tumour cells rather than myoepithelial cells should be considered and alternative markers (SMA, smooth muscle myosin heavy chain or calponin) would be useful, with the staining pattern being interpreted in the context of the morphology.
