Mucoepidermoid carcinoma of the esophagus. Report of an unoperated autopsy case and review of literature.

The esophageal tumor which occurred in a 53-year old female and was histologically similar to the salivary mucoepidermoid carcinoma, showed local invasion at autopsy. No distant metastasis was noted. Our literature review showed invasive and metastatic nature of the tumor. Submucosal location of the tumor in our case supported the proposed origin of the neoplasm from the esophageal gland.
