Overview
Pathogenesis
- Neurofibromas arise from nonmyelinating-type Schwann cells.[1]
- Plexiform neurofibromas can grow from nerves in the skin or from more internal nerve bundles, and can be very large.[2]
- About 10% of plexiform neurofibromas undergo transformation into a malignant peripheral nerve sheath tumor (MPNST).[3]
Gross Pathology
Microscopic Pathology
Genetics
- NF1 is involved in the pathogenesis of plexiform neurofibroma.[4]
