Appendiceal mass in a neonate after surgery for esophageal atresia and tracheoesophageal fistula: report of a case.

A 23-day-old girl presented with abdominal distension and vomiting. She had been previously operated on for esophageal atresia and tracheoesophageal fistula (EA/TEF) when she was 2 days old. An immediate laparotomy revealed an appendiceal mass caused by perforated appendicitis. The occurrence of appendicitis and an appendiceal mass is extremely rare in neonates and this may be the first such report in the world literature.
