The etiopathogenesis of nasal allergic polyps is poorly understood; an immunological mediated mechanism is commonly admitted. A clinic-pathological study of 92 cases of nasal polyps is reported. The occupational and or environmental background of the patients was recorded. Appropriate histochemical techniques were applied to identify pollutants within the lesions. Iron, wood, cement, cork, paper, glass, tobacco, textile fibres and chalk could be identified. The follow-up of patients at 12 years after excision of polyps revealed a decrease in recurrence whenever exposure to pollutants was discontinued. The etiology of nasal allergic polyps is probably related to the inhalation of some foreign materials reported.
鼻息肉的发病机制尚不清楚；免疫介导机制通常被认可。本文报道了一项对92例鼻息肉患者的临床病理研究。记录了患者的职业和/或环境背景。应用适当的组织化学技术来识别病变内的污染物。可识别出铁、木材、水泥、软木、纸张、玻璃、烟草、纺织纤维和白垩。息肉切除术后12年对患者的随访显示，一旦停止接触污染物，复发率就会降低。鼻息肉的病因可能与吸入某些报道的外来物质有关。
