Throat | Otorhinolaryngology | Esophageal cyst (Disease)
An esophageal cyst is a duplication of the esophagus usually involving the distal third of the esophagus. The esophagus is the tube that connects the mouth to the stomach. The cysts can compress surrounding structures causing difficulties swallowing, problems breathing, or heart arrhythmias. This disorder is rare and many patients do not have any symptoms.
Causes and Risk factors
Retention cyst is usually located in the lower esophagus and is lined by squamous epithelium or cuboidal cells and is probably related to post-inflammatory cystic dilatation of excretary duct of submucosal esophageal gland.
Esophageal duplication cysts are rare congenital anomalies lined by esophageal, bronchial or gastric type epithelium. 60% of duplication cyst is located in the lower esophagus. Foregut duplications occur as a result of abnormal canalization of the foregut during intrauterine life.
Symptoms may include chest pain, swallowing problems, breathing problems, vomiting blood.
