A nondiabetic neurotrophic ulcer of the heel.

This case deals with the etiology and treatment of a pure neurotrophic ulcer of the foot, an uncommon lesion. It is primarily caused by increased collagenolytic activity of anesthetic skin over a bony prominence. This type of ulcer in the heel is best treated by a skin flap from an adjacent innervated area of the plantar aspect of the foot. A split thickness skin graft covers the donor site.
