Complications of trichobezoars: a 30-year experience.

We have reported the case of a mildly retarded woman in whom an obsessive-compulsive disorder of hair eating (trichophagia) had begun between 2 and 3 years of age. Over the next 30 years, multiple complications of trichophagia included trichobezoars, malnutrition, intestinal obstruction, and ulceration with bleeding. One of the bouts of intestinal obstruction was associated with the superior mesenteric artery blocking the duodenum. This complication has not been reported previously in this disorder. The patient's trichotillomania (hair pulling) was treated with psychotherapy, behavior modification, and various medications, without success. The tricyclic antidepressant clomipramine (Anafranil) may be of benefit in such cases.
