Core Tip
Core Tip: Esophageal choristoma is an extremely rare congenital anomaly in neonates. This case report presents the clinical features, challenging yet successful diagnosis, and definitive treatment of a large esophageal choristoma in a 12-day-old infant. Notably, it describes the first documented case of complete endoscopic mucosal resection performed in a neonate using a slim endoscope, demonstrating endoscopic mucosal resection as a safe, effective, and minimally invasive curative option for pediatric esophageal masses.
