title: [Esthesioblastoma of the nose].
abstract: Morphological investigations of biopsy materials in 8 cases of esthesioblastomas of the nasal cavity were carried out. The three morphological variants of the tumour are described: esthesioneuroepithelioma, esthesioneurocytoma, and esthesioneuroblastoma. Rare occurrence of esthesioblastomas, peculiar features of their histological structure and difficulties of diagnosis in histological verification are emphasized. Lymphosarcoma is recommended to be differentiated from nondifferentiated cancer and sympathoblastoma. An important differentially-diagnostic procedure is considered to be a positive reaction to argentation (for identifying neurofibrils).
