Stasis dermatitis or venous stasis dermatitis is a change in the skin that occur when blood collects (pools) in the veins of the lower leg. ‘Stasis’ refers to pooling of the blood in the lower legs from venous insufficiency, and ‘dermatitis’ refers to the inflammation and related skin changes. Because of the inflammation, the skin around the ankles is usually itchy and discolored.
At first, the skin of the ankles and lower legs may look thin or tissue-like. You may slowly get brown stains on the skin.
The skin may become irritated or crack if you scratch it. It may also become red or swollen, crusted, or weepy.
Over time, some skin changes become permanent:
- Thickening and hardening of the skin on the legs and ankles (lipodermatosclerosis)
- A bumpy or cobblestone appearance of the skin
- Dark brown color
Skin sores (ulcers) may develop (called a venous ulcer or stasis ulcer). These most often form on the inside of the ankle. For this reason, whenever stasis dermatitis or skin changes are noticed around the ankle, you should see your doctor or vein specialist to stop the progression of venous insufficiency and prevent the skin from forming an ulceration.
