Interdigital neuroma. Morton neuromas are rarely seen in patients less than 20 years of age (Kasparek & Schneider, 2013), a congenital pacinian neuroma has been reported (Altmeyer, 1979), and although palisaded encapsulated neuromas do occur in children, they tend to affect middle-aged patients (Hall & Ferringer, 2013). adj.. 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. However, the term “neuroma” can be used to refer to any tumor (or swelling) of a nerve or its surrounding structures.

However, the large numbers of nerve bundles seen on skin biopsy are distinctive. Once these regions of aberrant activity are established, ectopic discharges can be evoked by mechanical stimulation and changes in the local environment, including increased concentration of catecholamines, ischemia, and electrolyte disturbances. It is also a general term used to describe any swelling of a nerve. The most common locations include the nose, cheek, and perioral region, especially the palate. Associate Editor, in High Yield Orthopaedics, 2010. The constant irritation causes fibrosis and deposition of collagen around the nerve fibers and ultimately the formation of a spindle neuroma. They are characterized by an intact perineural sheath with increased fibrous tissue deposition from chronic irritation of the intact nerve. In contrast to spindle neuromas, a lateral neuroma forms if the axon, the perineurium, and fascicles are partially disrupted. Acoustic neuroma is found in the skull and affects hearing. The classic neuroma demonstrates regenerating nerve fibers that are randomly oriented within scar tissue (Fig. 147-2. 2.23). The nerve can be dissected back, and its fascicles can be separated from the ulnar nerve, allowing it to be transposed proximal to the wrist between the flexor digitorum sublimis (FDS) and flexor digitorum profundus muscles. The incidence of Morton’s neuroma is 8 to 10 times greater in women than in men. A history of other MEN 2B–associated lesions also strongly favors mucosal neuroma. A neuroma may form any time a nerve is cut, and despite multiple surgical techniques to prevent neuromas, such as electrocautery, perineural closure, and silastic capping, most surgeons will cut the nerve proximal to the bone stump and allow it to retract into the stump, hoping to avoid a painful neuroma. Surgical removal of the growth may be necessary if other treatments fail to provide pain relief. Jennifer Baccon, ... Elias B. Rizk, in Nerves and Nerve Injuries, 2015. Another common term associated with neuroma is “traumatic neuroma”.

Interdigital neuroma, plantar view. Magnetic resonance imaging or ultrasound testing can be used to confirm the diagnosis if necessary. More rapid relief of symptoms can follow a local cortisone injection. People with certain foot deformities—bunions, hammertoes, flatfeet, or more flexible feet—are at higher risk for developing a neuroma.
