The ductal cells markers (AE1-/AE3- and CK7-positive expression) and basaloid cells markers (p63-, S100-, and SMA-positive expression), added to a low Ki-67 proliferation index (≤2%), supported its differential diagnosis with adenoid cystic carcinoma, basal cell carcinoma, or canalicular adenoma. The gene discussed is KRT7; the disease is adenoid cystic carcinoma.
