Olfactory neuroblastoma.
Few neoplasms are unique to the sinonasal tract, but sinonasal undifferentiated carcinoma and olfactory neuroblastoma are malignant tumors which require unique management. Due to the rarity of these tumors, practicing pathologists are not always aware of their distinctive clinical, radiographic, histologic, immunohistochemical, and molecular features. These cases are frequently submitted for co...
متن کاملRadiation-Induced Olfactory Neuroblastoma
Olfactory neuroblastoma (ONB) is a rare, malignant neuroendocrine tumor with potential to develop outside the normal means and distribution of olfactory neuroepithelium. With four published cases, we present a patient with a frontal sinus ONB invading the dura after receiving whole brain radiation for non-Hodgkin Lymphoma 20 years before.

متن کاملOlfactory neuroblastoma: MR evaluation.
PURPOSE To evaluate MR in the diagnosis and staging of olfactory neuroblastoma. METHODS Five patients with histologically proved olfactory neuroblastomas were studied by MR. Four also had CT scans. RESULTS The extent of disease delineated by MR agreed with surgical findings and surgical staging of the tumor in all five patients. All cases of olfactory neuroblastomas originated in the nasal ...
متن کاملIntracranial olfactory neuroblastoma: evidence for olfactory epithelial origin.
AIMS To determine the possible histogenesis of the intracranial variant of olfactory neuroblastoma. METHODS Four specimens from three cases of intracranial olfactory neuroblastoma were studied by light microscopy and immuno-histochemistry, and electron microscopy in two cases. RESULTS Light microscopical examination showed small cell tumour with additional features of epithelioid cells in o...
