Meckel's diverticulum (MD) is a congenital disorder of the gastrointestinal tract that is usually asymptomatic. Perforation of an MD by foreign bodies is an extremely rare cause of acute abdomen in children. We present a rare case of perforation of an MD in a child after eating melon seeds. The patient was treated successfully with segmental resection and primary anastomosis and had an uneventful postoperative recovery.
