"Trichobezoar" is the medical name for a hairball, which occurs as a result of "trichophagia" - the eating of one's own hair (from the Greek for "hair eating"). The largest trichobezoar surgically removed from a human was a hairball weighing 4.5 kg (10 lb) found in the stomach of an unnamed 18-year-old woman treated at Rush University Medical Center in Chicago, Illinois, USA, in November 2007. The excised trichobezoar measured 37.5 x 17.5 x 17.5 cm (15 x 7 x 7 in).
