Rapunzel syndrome (RS) is a rare condition presenting with hair accumulation in the stomach that extends to small intestine. It may cause gastric outlet and intestinal obstruction. The most common clinical signs are abdominal pain, palpable mobile mass and vomiting. A 12-year-old girl with a history of trichotillomania, trichophagia, attention deficit and hyperactivity disorder presented with gastric outlet obstruction. A bezoar completely filling the stomach and reaching to third part of the duodenum was detected in abdominal ultrasound. Removal of the trichobezoar via gastrotomy was the treatment of choice. Herein we report a 12-year-old girl with RS to discuss the clinical features and treatment options in this rare presentation.
