Abstract
This report is of an 82-year-old woman with a mass on the mandibular gingiva, elevated serum carcinoembryonic antigen, and a history of metachronous primary tumours of the endometrium and stomach. The histological diagnosis was tubulopapillary adenocarcinoma and the pathological features were similar to those of the gastric tumour. Consequently, the gingival mass was diagnosed as a metastatic gastric adenocarcinoma.

Key words:
Adenocarcinoma, Carcinoembryonic antigen, Gingival neoplasms, Immunohistochemistry, Metastasis
