The American Academy of Family Physicians and SkinSight both have pictures of venous skin ulcers. A venous skin ulcer is also known as a stasis ulcer, according to the AAFP. Approximately 1 percent of the United States population suffer from this condition, which is most common on the lower extremities.
When considering only lower extremity skin ulcers, venous skin ulcers account for 80 percent, notes the AAFP. The ulcers are usually shallow and have an irregular shape. Compression therapy is the accepted treatment for stasis ulcers because a Cochrane review noted that these lesions heal more slowly without compression therapy. Possible compression therapy options include intermittent pneumatic compression, elastic compression and inelastic compression.
