Skin Ulcer

	Decubitus Ulcer - An ulceration caused by prolonged pressure in patients permitted to lie too still for a long period of time. The bony prominences of the body are the most frequently affected sites. The ulcer is caused by ischemia of the underlying structures of the skin, fat, and muscles as a result of the sustained and constant pressure.
	Leg Ulcer - Ulceration of the skin and underlying structures of the lower extremity. About 90% of the cases are due to venous insufficiency (VARICOSE ULCER), 5% to arterial disease, and the remaining 5% to other causes.
