Lingual adenocarcinomas (ADC), either primary or metastatic to the tongue are extraordinarily rare neoplasms. Primary lingual adenocarcinomas are primarily of minor salivary gland origin. Two cases of primary colonic-type adenocarcinomas of the base of the tongue were recently reported for the first time in the English literature. We present an additional case of lingual intestinal-type adenocarcinoma with mucinous features that occurred in association with cervical node metastasis and discuss the clinicopathologic features and histogenetic aspects of this rare entity.
