<unk>  (45 x 30 mm). Classification A clinical severity score has been developed to assess chronic<unk> s. It is based on the CEAP (clinical, etiology, anatomy, and pathophysiology) classification system developed by an expert panel. A high score gives a poor prognosis. Distinction from arterial ulcer A<unk>  tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A<unk>  is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.<unk> s are typically 'wet' with a moderate to heavy exudate, whereas arterial ulcers are typically 'dry' and scabbed. The skin surrounding a<unk>  may be edematous (swollen) and there may be evidence of varicose veins; the skin surrounding an arterial ulcer may be pale, cold, shiny and hairless. Both<unk>  and arterial ulcers may be painful, however arterial ulcers tend to be more painful, especially with elevation of the leg, for example when in bed. Differential diagnosis Leg ulcerations may result from various pathologic processes. Common causes of leg ulcerations include inadequate blood flow and oxygen delivery to tissues as seen in peripheral arterial disease and<unk>  stasis ulcerations. Additional causes include neutrophilic skin conditions such as pyoderma gangrenosum or Sweet's syndrome; vasculitic processes such as cryoglobulinemia; calciphylaxis (often seen in people with end-stage kidney disease but may also occur with medications such as warfarin); cancers such as squamous cell carcinoma (Marjolin's ulcer) or myelodysplastic syndrome; neuropathy (e.g., diabetic peripheral neuropathy); or atypical infections such as nocardiosis, sporotrichosis, or mycobacterial infections.
