The Authors describe a case of a voluminous trichobezoar in a girl 9 years old. The patient was referred for evaluation of abdominal pain that presented after a banal blunt abdominal trauma occurred some days earlier. On physical examination an epigastric mass was detected. For a few days the girl suffered of inappetence and postprandial vomit. She was noted to have thin and sparse hair, thin eyebrows and onychodysplasia: these findings were considered as features of cutaneous adnexa dystrophy. The blood test and other laboratory findings were within normal limits. Abdominal US and UGI series failed to detect the nature of the mass. Therefore the patient underwent gastroscopy that showed a voluminous trichobezoar, so big and hard that gastrotomy was required for removal. The weight of the mass was 700 g; it occupied the whole stomach from fundus to pylorus. Postoperative recovery was uneventful. After discharge the patient was referred to the Neuropsychiatric Service for treatment trichophagia and prevention of recurrence. The most common site of trichobezoar is stomach. Clinical findings are often aspecific. US and UGI series may not allow the correct diagnosis. A rational diagnostic suspicion can arise when alopecia circumscripta is present. Endoscopy remains the elective technique: this procedure can be contemporarily diagnostic and therapeutic. Surgical approach is required only in case of trichobezoar with peculiar size, shape and hardness. We feel that a neuropsychiatric support is necessary to avoid recurrence.
