Heterotopic salivary gland adenocarcinoma in the cervical region

A case of heterotopic salivary gland adenocarcinoma (HSGA) in the right cervical region is presented. The carcinoma cells were positive for alpha-amylase, carcinoembryonic antigen, epithelial membrane antigen, cytokeratin as well as for expression of human salivary alpha-amylase messenger ribonucleic acid. The possibility of HSGA should be considered when an adenocarcinoma producing human salivary alpha-amylase is diagnosed away from sites where major and minor salivary glands normally are found.
