A neurilemoma (NL) is a benign, usually encapsulated neoplasm derived from Schwann cells and, along with neurofibroma, constitutes one of the 2 most common benign peripheral nerve sheath tumors. NLs may affect any location in the course of the peripheral nervous system (ie, cranial and spinal nerve roots, cranial and peripheral nerves, end organ receptors, small nerve twigs). They are common in paravertebral locations and the flexor regions of the extremities (especially near the elbow, wrist, and knee) and occasionally involve the skin.
