Congenital esophageal duplication cyst: report of two cases.

Esophageal duplication cysts account for a small percentage of benign esophageal tumors and are frequently asymptomatic. Diagnosis is difficult, and patients often seek treatment when complications such as respiratory distress, bleeding, or infection develop. Surgical excision is recommended at the time of cyst discovery whether or not symptoms are present. We report 2 newborn cases with esophageal duplication cysts. Symptoms included respiratory distress and palpable neck mass. Computed tomography demonstrated cystic masses in the retropharyngeal space. Both patients underwent surgical resection of the cyst and the symptoms were relieved. Histopathologic examination revealed esophageal duplication cysts.
