An Unusual Presentation of Metastatic Colon Adenocarcinoma in the Oral Cavity

Abstract

Background . A case report of a nonhealing ulcer of the tongue histologically proven to be adenocarcinoma. Method . A 92-year-old man underwent clinical, immunochemistry, and imaging investigation. Results . Tests confirmed a distant metastasis of a primary colorectal carcinoma. Conclusion . Metastasis from colorectal carcinoma to the oral cavity is primarily to bone, but non-healing ulcers of the oral cavity should be considered in differential diagnoses.
