title: A new histochemical approach to olfactory esthesioneuroma. A nasal tumor of neural crest origin.
abstract: A close collaboration between E.N.T. surgeons and pathologists permitted us to obtain 6 cases of olfactory esthesioneuroma in which fresh tumor tissue was available. Histochemical and biochemical studies were made in comparison with neuroblastoma. Different reactions and assays performed revealed a similarity with sympathetic tumors. Moreover, the presence of catecholamines in esthesioneuroma provides a great help in diagnostic as does electron microscope examination.
