Geographic Tongue - A well-defined, flat, rounded red area could be observed on the lingual dorsum; a mild coating of plaque could also be seen on the tongue (Panel A). A diagnosis of geographic tongue, also known as benign migratory glossitis, was made on the basis of the patient’s clinical history and the pathognomonic sign of the migrant red lingual patch. #Clinical #ENT #GeographicTongue #Geographic #Tongue #NEJM
