description: A rare adenocarcinoma of the major and minor salivary glands, originating from basaloid, myoepithelial and ductal cells. While morphologically resembling basal cell carcinomas, it is a distinct entity. The tumor is not encapsulated, may invade locally, and less frequently may metastasize. It usually occurs in older patients.
