Pedal plexiform neurofibroma: review of the literature and case report

Plexiform neurofibroma typically occurs in the setting of neurofibromatosis type 1, and is included in the diagnostic criteria for neurofibromatosis. Plexiform neurofibromas generally affect larger peripheral nerves and are uncommon in the foot and ankle. While there are several reports of large neurofibromas involving the foot, they have been described on the plantar aspect. We report the first known case of plexiform neurofibroma involving the deep peroneal nerve of the foot. A review of the literature is also presented.
