Congenital esophageal cysts--two cases in adult patients.

Esophageal cysts are a rare clinicopathological condition. They usually cause respiratory symptoms in children, while they are often asymptomatic in adults. Two cases of esophageal cysts in adults, recently diagnosed and treated in our department, are reported. In the 1st case (a 52 year-old woman) dysphagia was the main symptom. In the 2nd one (a 39 year-old woman) the patient was asymptomatic. Both were surgically excised by enucleation, with no post-operative complications. The histological study showed both cysts to be lined with ciliated cylindrical epithelium, and they were therefore considered to be congenital. Smooth muscle was only seen in the cyst wall in the 2nd case, but it was not organized in 2 layers, as is typical of duplication cysts. Cartilage or respiratory glands, the pathognomonic features of bronchogenic cysts, were not identified in either of them. Therefore, the diagnosis was inclusion cysts in both cases.
