title: Primary colonic-type adenocarcinoma of the base of the tongue: a previously unreported phenotype.
abstract: Primary lingual adenocarcinomas are rare and typically of salivary or seromucinous glands origin. Similarly, metastatic adenocarcinoma from distant primary sites to the tongue is an uncommon event, with only 3 cases from a colonic primary site reported. We present, for the first time, 2 primary colonic-type adenocarcinomas of the base of the tongue and discuss their putative origin and the clinicopathologic characteristics.
