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.
一名35岁男性，有呕血、上腹部疼痛症状，且无导致胃排空延迟的诱发因素，经检查发现有胃石。需要进行手术切除。病理和生化检查显示肿块由聚苯乙烯组成。这代表了一种不寻常的成分以及一种新发现的胃石形成诱发因素，即因摄入泡沫塑料杯导致的“聚苯乙烯癖”。
