Neurofibroma
What is a neurofibroma?
Neurofibromas are benign (non-cancerous) tumors that develop within the protective lining of a nerve. This is the most common type of nerve sheath tumor.
What causes neurofibroma?
Neurofibromas are caused by a DNA mutation which causes overgrowth of normal tissue. There is a genetic condition called neurofibromatosis, which is characterized by changes in the skin color (café-au-lait spots) and neurofibroma growth throughout the body.
Who is at risk for neurofibroma?
Those with a family history of neurofibromatosis 1 (NF-1) are at risk.
What are the symptoms of neurofibroma?
Depending on the nerve that the tumor is within, there is often pain in the affected area, weakness, and at times a palpable mass under the skin.
How is neurofibroma diagnosed?
- Patient history
- Physical exam
- Imaging: ultrasound, MRI
- Biopsy: a biopsy is the only definitive way to diagnose a tumor
How is neurofibroma treated?
Nonsurgical
Monitor with imaging
Surgical
If the tumor is causing symptoms, it can often be surgically removed.
