Rapunzel syndrome or gastrointestinal trichobezoar is caused by hair ingestion. The diagnosis may be suspected in young females with important weight loss, who deny hair eating. We report a 16 year-old female consulting in the emergency room for abdominal pain. She was subjected to an exploratory laparotomy and a big mass was palpated in the stomach. A gastrostomy and enterostomy were performed and a 17 x 6 x 5 cm trichobezoar was extracted. The patient had an uneventful postoperative outcome and was derived to Psychiatry.
