Overview

A neurofibroma is a type of nerve tumor that forms soft bumps on or under the skin. A neurofibroma can develop within a major or minor nerve anywhere in the body. This common type of benign nerve tumor tends to form more centrally within the nerve. Sometimes it arises from several nerve bundles (plexiform neurofibroma).

Symptoms are often mild or absent. If the tumor presses against nerves or grows within them, you may experience pain or numbness in the affected area.

A neurofibroma is usually noncancerous (benign). Rarely, it can become cancerous (malignant).
