Physical examination of the abdomen revealed a palpable mass in the epigastric and left upper quadrant regions. It was also noted areas of alopecia of the scalp.
  
  
  CONCLUSIONS
  Ninety percent of the trichobezoars present in females with a high frequency between 10-19 years. The treatment of bezoars (unless small in size) is mainly surgical. A psychiatric evaluation and follow up is important after surgery hence in most cases there is a psychological disorder that lead to the ingestion of hair.
