Cytokeratin 5 dimerizes with Cytokeratin 14 to form the cytoskeleton of basal epithelial cells, while Cytokeratin 6 multimerizes with Cytokeratin 16 and/or 17 in the tongue, oral epithelia and esophagus, hair follicles, and glandular epithelia. Anti-Cytokeratin 5 & 6 rarely stains lung adenocarcinoma, but will produce small foci or scattered staining pattes in these Cytokeratin 5 & 6(+) samples. Cytokeratin 5 & 6 staining is useful for identifying squamous cell carcinoma, and can be used to determine the malignancies of myoepithelial cells in the breast and prostate. Cytokeratin 5 & 6 also rarely stains carcinomas of the breast, colon, and prostate. A panel of antibodies against Cytokeratin 5 & 6, TTF-1, napsin A, p63, SOX2, DSC3, and desmoglein-3 is useful for differentiating lung squamous cell carcinoma from lung adenocarcinoma and large cell carcinoma.
