Trichobezoars are gastric foreign bodies rarely found in children. They are mainly composed of swallowed hair. Rapunzel syndrome is a very rare form of trichobezoar characterized by extension of the ingested hair from the stomach into the small intestine or even beyond. Clinical presentation can range from an asymptomatic abdominal mass to severe symptoms: gastric outlet obstruction, perforation of the stomach, and acute pancreatitis. Trichobezoars are usually treated with surgical removal. Here we present the case of an 8-year-old girl in whom a firm non-tender mass in the epigastric region was palpated during a regular outpatient clinic visit. The girl reported some slight abdominal discomfort and early satiety during meals. Subsequently, focal alopecia was detected. A trichobezoar in the stomach with some extension into the duodenum was diagnosed by ultrasound, and later confirmed by a barium swallow study and CT scan. The trichobezoar was successfully surgically removed.
