Trichotillomania resulting in a trichobezoar: a case report.

This paper presents a case of a 19-year-old, 10 1/2-week-pregnant woman with trichotillomania that resulted in a trichobezoar. The case illustrates typical presentation, patient behavior, symptomatology, and physical findings of patients with trichobezoars. The hypothesized methods for trichobezoar formation, complications, and treatment are discussed. The diagnostic criteria, epidemiology, and treatment of trichotillomania are also discussed.
