neuroma

 [noo͡-ro´mah]
a tumor or new growth largely made up of nerve cells and nerve fibers. adj., adj neurom´atous.
acoustic neuroma a benign tumor within the auditory canal arising from the eighth cranial (acoustic) nerve. Hearing loss begins in the teens or early 20's and may be surgically managed. Acoustic neuroma is a manifestation of Type II neurofibromatosis.
amputation neuroma traumatic neuroma occurring after amputation of a limb or other part.
neuroma cu´tis neuroma in the skin.
false neuroma one that does not contain nerve elements.
plexiform neuroma one made up of contorted nerve trunks.
neuroma telangiecto´des one containing an excess of blood vessels.
traumatic neuroma an unorganized bulbous or nodular mass of nerve fibers and Schwann cells produced by hyperplasia of nerve fibers and their supporting tissues after accidental or purposeful sectioning of the nerve.

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 telangiecto´des  one containing an excess of blood vessels.
traumatic neuroma  a nonneoplastic, unorganized, bulbous or nodular mass of nerve fibers and Schwann cells produced by hyperplasia of nerve fibers and their supporting tissues after accidental or purposeful sectioning of the nerve.

neuroma

(no͝o-rō′mə, nyo͝o-)
n. pl. neuro·mas or neuro·mata (-mə-tə)
A tumor composed of nerve tissue.

neuroma

[noo͡rō′mə] pl. neuromas, neuromata
Etymology: Gk, neuron + oma, tumor
a benign neoplasm composed chiefly of neurons and nerve fibers, usually arising from a nerve tissue. Pain radiating from the lesion to the periphery of the affected nerve is usually intermittent but may become continuous and severe.

neu·ro·ma

, pl. neuromata, pl. neuromas (nūr-ō'mă, -mă-tǎ, -măz)
General term for any neoplasm derived from cells of the nervous system, e.g., ganglioneuroma, neurilemmoma (schwannoma), pseudoneuroma.
[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.

neuroma (nyoorō´mə),

n technically, a benign neoplasm of nerve cells. As used in oral disease, the term usually refers to a traumatic neuroma, which is not a true tumor but an overgrowth of nerves associated with injury. The mental foramina and extraction scars are possible oral sites of this painful lesion.
neuroma, amputation,
n See neuroma, traumatic.
neuroma, multiple,
neuroma, traumatic,
n (amputation neuroma), hyperplasia of nerve fibers and their supporting tissues in an exuberant attempt at repair after damage to, or the severing of, a nerve.
