A bezoar (/ˈbizɔːr/ BEE-zor) is a mass often found trapped in the gastrointestinal system, though it can occur in other locations. A pseudobezoar is an indigestible object introduced intentionally into the digestive system.
There are several varieties of bezoar, some of which have inorganic constituents and others organic. The term has both modern (medical, scientific) and traditional usage.
