We show an unusual presentation of a schwannoma that was located in the ungual bed of the left great toe. The clinical, color Doppler ultrasound imaging, and histologic findings are shown to illustrate the case. This type of neurogenic tumor and the ultrasound presurgical imaging support should be considered when dealing with subungual tumors of the foot.
