A schwannoma is a slow-growing, neurogenic tumor composed of Schwann cells arising from a peripheral nerve sheath. The authors present a rare finding of a schwannoma of the sural nerve that was overlooked in a 51-year-old female with radiating foot pain. This case highlights the clinical implications and important teaching points in recognizing a schwannoma of the foot.
