[Cystic duplications of the esophagus in adults. Report of 2 cases].

Oesophageal duplications account for less than 10% of the benign tumors of the oesophagus and for 20% of intestinal duplications. They are most often seen during childhood. In the adult it is more often the non communicating cystic forms, which are prone to complication, which have been reported. Cervical localization is rare and up to now no case has been described in the adult. We report here an asymptomatic case. Our second patient, who had a duplication in the mediastinal region, presented with a cough and dysphagia which completely regressed after excision.
