[Papilloma of the larynx. Immunology (author's transl)].

Electron-microscopic and immunohistological studies show the cross-reactivity of an antigen in verruca plana, condyloma acuminatum and laryngeal papilloma. If this antigen is identical with papova virus or a tumor-performed antigen, cannot be distinguished definately. The fact that sera of patients bearing condylomata acuminata show strong antigen-antibody-reaction with tissue-sections of laryngeal papilloma by means of immunofluorescence microscopy, is discussed in a probably therapeutical point of view.
