Superficial Peroneal Nerve Schwannoma.

ABSTRACT: Schwannomas are benign tumors of the nerve sheath that arise from the proliferation of active peripheral Schwann cells. Although schwannomas are the most common benign peripheral nerve sheath tumors, superficial peroneal nerve schwannomas are rare in published works of literature.
