[Neuroblastoma of the olfactory nerve]

Abstract

The histopathology of neuroblastomas of the olfactory nerve, especially the difficult differential diagnosis is described by means of our own observations, and compared with other less differentiated malignant tumours of the inner nose. Ultrastructural results are presented, histogenesis and classification of olfactory neuroblastomas in neuroepithelioma, neurocytoma and neuroblastoma are discussed. The literature is reviewed, whereby clinical symptoms, therapy and prognosis of these tumours are described.
