Leg ulcer of unknown etiology

Leg ulcers are the bane of the surgeons existence. These ulcers are common in Nigeria from various causes. Occasionally, I use an old fashioned method of treatment-the Unna BootUnna Boots are named after a German dermatologist, Paul Gerson Unna. Dr. Unna specialized in diagnosing and treating diseases of the skin. The Unna Boot itself is a compression dressing, usually made of cotton, that has a zinc oxide paste applied uniformly to the entire bandage. The zinc oxide paste in the Unna Boot helps ease skin irritation and keeps the area moist. The zinc promotes healing within wound sites, making it useful for burns and ulcers.
