Elevated Serum Carcinoembryonic Antigen Levels with Sublingual Mucoepidermoid Tumor; A Case Report

Abstract

Although elevated serum CEA levels have been reported in association with a variety of tumors including those arising from the epithelia of the colon, rectum, stomach, pancreas, lung, breast, female reproductive tract, and urinary bladder, this association has not previously been reported for patients with salivary gland tumors.
Here, we report a 71-year-old male with sublingual mucoepidermoid tumor. He was admitted to our hospital because of elevated serum carcinoembryonic antigen levels, and an examination of his upper GI tract and colon in addition to a urological examination and otolaryngolical examination were conducted. A sublingual mucoepidermoid tumor was subsequently diagnosed, and the patient underwent radical surgery to remove the tumor. The postoperative course was uneventful and the patient's serum CEA level decreased to within normal range.
