Lipodermatosclerosis refers to changes in the skin of the lower legs. It is a form of panniculitis (inflammation of the layer of fat under the skin). Signs and symptoms include pain, hardening of skin, change in skin color (redness), swelling, and a tapering of the legs above the ankles. The exact underlying cause is unknown; however, it appears to be associated with venous insufficiency and/or obesity. Treatment usually includes compression therapy.
