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.

In fact the condition had already been well described by the British practitioner; Lewis Durlacher (1792 -1864), Surgeon-Chiropodist to the British Royal Households of King George IV, King William IV and Queen Victoria, although, naturally, Durlacher did not call it 'Mortons Neuroma (Durlacher 1845), instead referring to a 'Metatarsalgia'.
Aunque se han propuesto otras muchas causas (alteraciones o variantes anatomicas en los metatarsianos o en los nervios perifericos distales o el uso de calzado antifisiologico (10,11,12,13)), esta generalmente aceptado que, originariamente, la etiologia mas frecuente de los neuromas interdigitales del pie es traumatica o microtraumatica/ patomecanica.
If you have pain between the third and fourth toes, you most likely have a Morton's neuroma. This is swelling or scarring of the nerve.
