neuroma

A neuroma (pronounced /nuːˈroʊmʌ/) is a growth or tumor of nerve tissue.[1] (Neuro- is from the Greek for nerve, whereas the suffix -oma denotes swelling.) Just as the Latin word for swelling (tumor) is now restricted to neoplasias, the equivalent Greek suffix -oma has shared in that fate. Thus, the typical modern usage of neuroma is for nerve tumors. However, many of the older, more general uses persist.

Also a neuroma is when a nerve is severed during amputation, the nerve endings form a mass (neuroma) reminiscent of a cauliflower shape. Neuromas can be troublesome, especially when they are in places that are subject to pressure from the socket. They can also cause an amputee to experience sensory phenomena in or around the residual limb, which can be aggravating and/or painful.
