A seven-year-old girl presented to us with early satiety, abdominal distension, and loss of weight. There was a history of hair eating; however, there was no history of vomiting, fever, or diarrhea. On examination, there was a firm well-defined lump palpable in the left hypochondrium of size 3.5 cm. Computerized tomography (Fig. 1) was done with concern of a possible tumor. It showed presence of well-defined intraluminal heterogenous mass with mottled appearance present in the stomach and extending into the duodenum (D4). Upper gastrointestinal endoscopy confirmed the mass as trichobezoar. The patient underwent explorative laparotomy and anterior gastrotomy where trichobezoar was removed en bloc (Fig. 2). Histopathology showed hair bundles along with vegetative material, decaying necrotic material, and many thin-walled fungal hyphae with acute angle branching. The patient was allowed orally after four days and discharged after seven days. Parents were counselled to get psychiatric consultation for the patient to prevent recurrence. Bezoars are concretions in the gastrointestinal tract that increase in size by continuous accumulation of non-absorbable food or fibers. Most common bezoars in children are trichobezoars formed by swallowed hair from the head, dolls, or brushes. Hair being slippery evades peristalsis and gets entrapped in gastric mucosal folds. More and more hair conglomerate to form a stomach-shaped mass coated with mucus called trichobezoar [1]. This provides a shiny glistening surface, and the gastric acid denatures the hair protein giving it the typical black color [2]. Trichobezoars typically cause abdominal pain and nausea, but can also present as an asymptomatic abdominal mass, progressing to abdominal obstruction and perforation. Rarely bezoar may extend from the stomach to the small intestine or beyond and is described as Rapunzel syndrome. The name “Rapunzel” syndrome comes from the Grimm Brothers’ fairy tale of a twelve-year-old princess who was shut into a tower with neither stairs nor doors by an enchantress who climbed up the tower’s walls with the help of Rapunzel’s long tresses [3]. When a bezoar is suspected, the history should focus on trichotillomania and ingestion of items, such as doll or pet hair. Severe halitosis and patchy alopecia provide clues on physical examination [4]. Imaging may show the bezoar as a mass or filling defect. The gold standard for diagnosis is upper gastrointestinal endoscopy. The management and treatment of a Rapunzel syndrome encompass surgical removal of the mass and prevention of recurrence by addressing the underlying psychiatric disorder. Surgical removal is accomplished by gastrotomy or enterotomy.
