Clinical Significance
CK14, a marker of squamous and basal epithelial phenotype, is most frequently used along with CK5/6 and P63 to diagnose the basal subset of breast carcinoma. CK14 expression is also characteristic of oncocytic tumors at various tissue sites and can be used to differentiate these tumors from other epithelioid neoplasms, such as conventional renal cell carcinoma.
