title: Trichobezoar, rapunzel syndrome, tricho-plaster bezoar - a report of three cases.
abstract: BACKGROUND
  Trichobezoar is an uncommon entity observed mostly in young women. Symptoms in presenting patients are usually due to the large mass of the bezoar or malabsorption of nutrients. Trichobezoar is almost always associated with trichotillomania and trichophagia.
  
  
  METHODS
  Three teenage girls, aged 13, 15, and 16, were diagnosed due to palpable epigastric masses. Additionally the oldest patient presented with symptoms of ileus while the other two patients had weight loss and anaemia. Besides the 15-year-old patient complained of paroxysmal abdominal pains. Patients were subjected to plain radiographic examinations of abdomen which revealed large epigastric tumours, with additional calcifications observed in the youngest girl. Subsequent gastroscopy (the 15-year-old patient) or ultrasonographic examination and computed tomography scans (13- and 16-year-old patients) allowed to establish the diagnosis of giant bezoars: trichobezoars in two older patients and tricho-plaster bezoar in the youngest one. All the tumours were surgically resected and psychiatric treatment was undertaken.
  
  
  CONCLUSIONS
  1. Trichobezoar should be taken into consideration in differential diagnosis of epigastric tumours in children, especially teenage girls. 2. The conventional ultrasonographic and radiographic examinations of the abdomen are insufficient for determination of the nature of the mass. A thorough medical history interview and clinical examination may give directions regarding the further diagnosis.3. Trichotillomania and trichophagia are obsessive-compulsive disorders, and therefore patients with trichobezoars should be under psychiatric care to prevent recurrence of the disease.
