Olfactory neuroblastoma with spinal metastasis--a problem in diagnosis.
The olfactory neuroblastoma or esthesioneuroblastoma is a rare neuroectodermal tumor originating from the olfactory neuroepithelium, which can metastasis via cerebrospinal fluid pathways. In the present case of an extensive nasal malignancy with cervical lymph node metastases in a 75-year old woman, its difficult histology alternatively led to a diagnosis of anaplastic carcinoma and non-Hodgkin lymphoma. The patient died from complications following spread of the tumor to the spinal cord and cauda equina. Review of the literature shows that this tumor is notorious for its chameleonic character. In view of its clearly demonstrated malignancy an aggressive therapeutic approach is advocated.
