Bezoars are concretions commonly found in the stomach and small bowel, and four types of bezoars have been described based on their composition : trichobezoar, phytobezoar, lactorbezoar, and miscellaneous. Bezoars most often develop after gastric operations that alter the motility, emptying, and grinding of food in the stomach. Trichobezoars are most common in female children with normal gastrointestinal function and are usually associated with pica, mental retardation, and psychiatric disorders. Although uncommon, bezoars are a well-recognized cause of chronic abdominal complaints which, when undiagnosed, can result in serious complications including gastric ulceration, bleeding, perforation, intussusception and small bowel obstruction. Mortality rates of up to 30 percent have been reported in adults. Trichotillomania is behaviors surrounding hair-pulling, including stroking and playing with hair before pulling, or biting and swallowing the hair after it has been pulled(trichophagia). The most notorious of the medical sequelae of trichotillomania is the trichobezoar. We experienced a case of trichobezoar in an 11-year-old girl who frequently swallowed her hairs from age 4 years up to age 7 years, resulting in intermittent abdominal pain, nausea, and vomiting.
