Living with Malignant peripheral nerve sheath tumor

A tumor that grows in the lining around nerves and often first appears as a growing lump.

Understanding Malignant peripheral nerve sheath tumor

Malignant peripheral nerve sheath tumor (MPNST) is a tumor that develops in the protective lining that covers nerves.

The first symptom is often a lump that grows and sometimes causes pain or tingling. It is considered aggressive because it can grow back after surgery and can spread to other parts of the body, most commonly the lung. It can happen at a variety of ages.

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
