An unusual case of solitary benign schwannoma of the foot is presented. Clinical examination, magnetic resonance imaging, and intraoperative findings all confirm the suspicion of a ganglion cyst. After attempted aspiration failed to produce any aspirate, excisional biopsy was performed. The pathology report confirms schwannoma with hematoxylin and eosin stain and subsequently reaffirmed with positive S100 protein stain. Even though schwannoma of the foot had been reported in the literature, this was an unusual case, as the lesion was presented as a superficial, ganglion cyst–like lesion on the bottom of the foot.
