Esophageal adenocarcinoma: a long-term complication of congenital diaphragmatic hernia?

A 22-year-old man presented with a lower esophageal adenocarcinoma having been treated for a left-sided congenital diaphragmatic hernia (CDH) as a neonate. There is no known association or similar case reported in the literature. We review the known long-term sequelae of CDH, possible theories for the occurrence of adenocarcinoma, and its implications for follow-up of patients with CDH.
