Schwannoma

Common Name(s)

Schwannoma

Schwannomas are tumors of the tissue that covers the nerves (nerve sheath). These tumors develop from a type of cell called a Schwann cell, which gives them their name. They are usually benign (not cancerous). Although schwannomas can arise from any nerve in the body, the most common areas include the nerves of the head and neck and those involved with flexing in the arms and legs. Common symptoms include a slow-growing mass and Tinel shock (an electric-like shock when the affected area is touched). The cause of schwannomas is unknown, but they sometimes occur in people with certain disorders including some types of neurofibromatosis. Benign schwannomas are typically treated with surgery.
