| neuroma cutis | Neurofibroma of the skin. (05 Mar 2000) |
| neuroma telangiectodes | A neurofibroma with a conspicuous number of blood vessels, some of which have unusually large lumens (in proportion to the thickness of the walls). Traumatic neuroma, the non-neoplastic proliferative mass of Schwann cells and neurites that may develop at the proximal end of a severed or injured nerve. Synonym: amputation neuroma, false neuroma, pseudoneuroma. Verneuil's neuroma, a nodular enlargement of the cutaneous nerves. (05 Mar 2000) |
| neuroma, acoustic | A progressively enlarging tumour within the auditory canal arising from the eighth cranial nerve. This solitary form is usually unilateral, tends to develop later in life, and is not inherited as compared to the acoustic neuromas arising in neurofibromatosis 2. (12 Dec 1998) |
| neuroma, optic | A benign tumour of the optic nerve. (12 Dec 1998) |
| neuromalacia | Pathologic softening of nervous tissue. Origin: neuro-+ G. Malakia, softness (05 Mar 2000) |
| neuromast | See: lateral line sense organ. (05 Mar 2000) |
| neuromast organ | A structure in fish consisting of a long groove or canal extending along each side of the trunk and tail and branching in the head region; the groove or tube is lined with neuroepithelial cells, some of which are in groups known as neuromasts; its function appears to be the detection of vibrations of low frequency. Synonym: neuromast organ. (05 Mar 2000) |
| neuromatosis | The presence of multiple neuromas, as in neurofibromatosis. (05 Mar 2000) |
| acoustic neuroma | <oncology, tumour> This is a benign tumour of the 8th cranial nerve. This tumour arises from the myelin forming Schwann cells that coat the 8th cranial nerve (acoustic nerve). Clinical presentation usually includes hearing deficit. Diagnosis can be made with auditory evoked potentials and/or MRI scanning of the brain. Vertigo and tinnitus may be associated symptoms. Surgical removal of this tumour involves dissection, cautery and obliteration with laser. Incidence: 1 in 100,000. (13 Nov 1997) |

| amputation neuroma | traumatic neuroma |
| Morton's neuroma | <oncology, tumour> A ganglionic swelling or ganglion cyst in the forefoot. Symptoms include pain in the forefoot and localised swelling. (27 Sep 1997) |
| plexiform neuroma | plexiform neurofibroma |
| multiple mucosal neuroma syndrome | <syndrome> Multiple submucosal neuromas or neurofibromas of the tongue, lips, and eyelids in young persons; sometimes associated with tumours of the thyroid or adrenal medulla, or with subcutaneous neurofibromatosis. (05 Mar 2000) |
| optic neuroma | A benign tumour of the optic nerve. (12 Dec 1998) |
| false neuroma | traumatic neuroma |
| fibrillary neuroma | plexiform neurofibroma |
