Neurofibroma is the formation of a tumour in the outer part of the nerves, known as the nerve sheath. It forms a soft elevation under the skin in any part of the body. It can occur in the major or minor nerves and is usually painless. The tumour is completely benign and rarely develops into cancer.

The nerves in your body are classified into two parts:

• The central nervous system includes the brain and the spinal cord.
• The peripheral nervous system consists of the major and minor nerves distributed from the central nervous system and reach the smallest parts of your body.

Neurofibroma is a tumour in the nerves of the peripheral nervous system. They usually develop within the form. If formed in multiple nerve bundles, they are called plexiform Neurofibroma.
