neu·ro·ma

(nū-rō'mă),
General term for any neoplasm derived from cells of the nervous system; on the basis of newer knowledge pertaining to cytologic and histologic characteristics, a variety of neoplasms, formerly placed in the general category of neuroma, may now be classified in more specific categories, for example, ganglioneuroma, neurilemoma, pseudoneuroma, and others.
[neuro- + G. -oma, tumor]

neuroma

A non-malignant (benign) tumour of nerve tissue consisting of a mass of nerve fibres. Although neuromas do not spread remotely their location, especially within the skull, may cause danger by compressing local structures. An acoustic neuroma is a tumour of the 8th CRANIAL NERVE.
