Colleta et al (13) reported that the majority of cancer cells of ACC express CK7, which indicates a ductal-pattern possibly of salivary gland origin, while in BSCC, the basaloid cells exhibit positive expression for CK17 and negative expression for vimentin, S-100, CK7, CK8 or CK20. The gene discussed is KRT7; the disease is adrenal cortex carcinoma.
