title: Polystyrene bezoar in a patient with polystyrenomania.
abstract: A 35-yr-old man with hematemesis, epigastric pain, and no predisposing factors to delayed gastric emptying was found to have a gastric bezoar. Surgical removal was required. Pathological and biochemical examination revealed a mass composed of polystyrene. This represents an unusual composition and a newly recognized predisposing factor to bezoar formation, "polystyrenomania" from ingestion of styrofoam cups.
