Lactobezoar causing an abdominal triad of colicky pain, emesis, and mass.

A case of lactobezoar is described in a toddler with an acute history of abdominal pain, vomiting, and lethargy. Despite normal dietary habits, he had developed a gastric milk coagulum which led to a palpable epigastric tumor. Intussusception was suspected but disproven by barium enema. In retrospect, plain abdominal radiographs demonstrated characteristic mottled filling defects in the stomach from a lactobezoar. Conservative therapy led to prompt disintegration of the lactobezoar.
