The latest issue of The New England Journal of Medicine features an unusual case of trichobezoar (tricho- for “hair”; bezoar for “indigestible mass in stomach or intestine”), otherwise known as a stomach hairball. The patient is an 18 year-old lady who presented to the Rush University Medical Center (Chicago, IL) with a 5-month history of abdominal pain and vomiting with meals. Computed tomography (CT) demonstrates a large mass in the stomach (see Figure A), which likely contributed to the reported symptoms. Esophagogastroduodenoscopy (EGD)–the insertion of a camera via the oral cavity and advanced to the upper segments of the digestive tract–was able to visualize the impressive bezoar (see Figure B), measuring 37.5 x 17.5 x 17.5 cm. It was later discovered the patient had a habit of eating her own hair (trichophagia). The only option for removal was open surgery. The extracted bezoar weighed 4.5 kg and can be seen in Figure C. Not surprisingly, the patient stopped eating her hair, experienced an improvement in symptoms, and eventually regained her weight.
