Elevated carcinoembryonic antigen tumour marker caused by head and neck cancer: A case report and literature study

摘要

Carcinoembryonic antigen is a tumour marker commonly increased in gastrointestinal and pulmonary cancers. We report a case of a 46-year-old man with a mucoepidermoid carcinoma of the base of tongue with an elevated and traceable serum carcinoembryonic antigen level. This antigen proved to be a valuable marker in the treatment follow-up. When a raised carcinoembryonic antigen level is found, salivary gland malignancies should be taken into the differential diagnosis and clinical examination of the head and neck region should not be overlooked.
