"Oesophageal duplication cysts typically present in childhood with symptoms of dysphagia, cough, stridor, pain or arrhythmias 4. They can occur anywhere along the oesophagus, and ~90% have no communication with the oesophageal lumen. More than half occur in the lower third of the oesophagus 4."
"They are a congenital malformation of the posterior primitive foregut and result from an aberration of the posterior division of the embryonic foregut at 3-4 weeks gestation. They are usually unilocular and contain mucin. The wall contains one or two smooth muscle layers, and the inner epithelial lining is variable and can include stratified squamous, simple columnar, pseudostratified columnar, cuboidal, and ciliated epithelium. Islands of heterotopic gastric or pancreatic mucosa can cause ulceration, haemorrhage and perforation. The cyst may contain mucin and detached ciliary tufts."
"Recognised complications rarely include carcinoma arising within the cyst 5. If gastric mucosa is present peptic ulceration may occur. Very occasionally they may perforate, haemorrhage or erode into adjacent structures."
