Carcinoma <i>ex</i> pleomorphic adenoma (CXPA): immunoprofile of the cells involved in carcinomatous progression

Abstract

Most CXPAs consist only of epithelial cells that have an immunoprofile comparable to ductal luminal cells of PA. These malignant luminal cells arise in the duct-like structures as intraductal carcinoma and probably only at this early stage of development should the lesion be considered as a non-invasive carcinoma.
