Synopsis

A traumatic neuroma, also known as an amputation neuroma, pseudoneuroma, and scar neuroma, is an uncommon, benign lesion that arises at site of prior trauma, surgery, amputation, or scar.

It is thought that these lesions develop as aberrant neural regeneration following injury. Traumatic neuromas develop within 1-10 years of the initial insult. The most common locations are the sites of tooth extraction, circumcision, limb amputation, and abdominal surgery. However, traumatic neuromas can occur anywhere on the body.

Traumatic neuromas have no specific predilection for gender or age. Some rudimentary supernumerary digits are considered a congenital variant of traumatic neuroma due to in utero amputation of a supernumerary digit. Symptoms depend on the type of nerve (motor versus sensory) involved; however, pain is the most commonly described symptom.

Many pathophysiological mechanisms for the development of traumatic neuromas have been hypothesized, but the exact mechanism is still unknown.
