[A duplication of the alimentary tract with unusual localization in the submaxillary region]

Duplication cysts developed from the intra-oral digestive tract are exceedingly rare lesions of which only 15 cases have previously been reported. We report an additional case in a neonate with a large cystic lesion in the right submandibular area. Clinico-pathologic findings are described and the literature is reviewed. Criteria for the diagnosis of digestive tract duplication are recalled. Differential diagnosis and etiopathogenic theories are discussed.
