title: Ectopic production of beta-human chorionic gonadotropin by inverted papilloma of the nose.
abstract: A series of 19 inverted papillomas (transitional type or Schneiderian papillomas) of the nose were examined using an immunogold-silver (IGS) technique and an indirect immunoperoxidase technique. We demonstrated beta-HCG production in all 19 specimens with both methods. The staining demonstrated by the IGS technique was of a greater intensity and in a larger number of cells than that observed by the indirect immunoperoxidase method.
