Abstract
A schwannoma is a benign neurogenic tumor derived from Schwann cells. A rare case of a large painful schwannoma in the foot with metatarsal deformity was presented. Due to suspicion of malignancy, amputation had been recommended previously. We report on a rare case of a large forefoot schwannoma causing pain and paresthesia of the forefoot.

Anteroposterior radiograph shows lateral angulation and sclerosis of second, third metatarsal shaft.
Figure 2.
The axial T2-weighted magnetic resonance image shows a heterogenous cystic mass with low to hyperdense signal intensity, with dorsal and plantar extension.
Figure 3.
(A) A excised mass was removed through plantar incision. (B) Clinical photograph after mass excision shows both a deep peroneal nerve and a common proper digital nerve derived from medial plantar nerve.
Figure 4.
(A) Gross photograph shows a well circumscribed and encapsulated mass. (B) The cross section of mass appears diffusely myxoid and grayish yellow cut surfaces without hemorrhage or necrosis.
