title: [Association of congenital upper and lower double lip].
abstract: The frequency of the congenital double lip is scarcely mentioned in the literature. There is no previous report on the bilabial congenital double lip. This association consists of a mucosae fold at the free edge of the lip, which is projected at smiling and opening of the mouth. Histologically, the mucous salivary glands are either hypertrophic or normal with little connective tissue and covered by a cornified epithelium. There is no muscle tissue found. We present the report of two cases of bilabial congenital double lip treated surgically by the elliptical resection of the mucosae folds.
