IHC Diagnostic Interpretation: The immunophenotypic profile—characterized by epithelial marker expression (AE1/AE3, CK7), positivity for CD117 and Bcl-2, and the presence of myoepithelial cells identified by p63, p40, and calponin—was highly consistent with adenoid cystic carcinoma of the larynx. Here, KIT is linked to adenoid cystic carcinoma.
