Definition / general
- Rare; mostly developmental unless due to cystic degeneration of tumor
- Simple cysts are epithelial lined; duplication cysts have 2 muscle layers (eMedicine: Esophageal Cysts [Accessed 16 January 2018], Arch Pathol Lab Med 1977;101:136)
- Either intramural or attached to outer layers of esophagus
- Often asymptomatic, even if large; may cause obstructive symptoms
- See also retention cysts

- Also called gastroenteric cyst, foregut cyst
- Congenital anomaly, usually lower esophagus
- Most are intramural; usually isolated anomaly; however, duplications external to esophageal wall may be associated with vertebral anomalies
- 90% do not communicate with esophagus
- Usually symptomatic causing dysphagia or respiratory difficulty
Case reports
- 22 day old boy (Indian J Pathol Microbiol 2006;49:396)
- 2 infants with respiratory distress (Pediatr Emerg Care 2005;21:854)

- 52 year old woman (Yonsei Med J 2005;46:859)
- 61 year old woman with squamous cell carcinoma (Br J Radiol 2003;76:343)
