Gastric perforation caused by a lactobezoar in an infant: a case report.
The lactobezoar contains undigested milk curds and the hard concretions are inorganic masses or calculi usually containing calcium.
Lactobezoar occurs in low birth weight infants fed with concentrated milk and formulas in the first week of life, pharmacobezoar occurs due the use of concentrated drug formulas (cholestyramine and kayexalate); and food bezoars occur due to the use of concentrated food formulas.
Bezoars can be classified in four types: phytobezoar (vegetable); trichobezoar (hair); lactobezoar (milk/curd) and miscellaneous (fungus, sand, paper, etc).
Bezoar may be classified as Trichobezoar (mass of hair), Phytobezoar (vegetable fiber), Diospyrobezoar (persimmons), Lactobezoar (inspissated milk), Pharmacobezoar (tablets/semiliquid mass of drugs) & miscellaneous (1, 8, 10).
