Lipodermatosclerosis (also known as "Chronic panniculitis with lipomembranous changes,"^[1] "Hypodermitis sclerodermiformis," "Sclerosing panniculitis," and "Stasis panniculitis"^[2]:489) is a skin and connective tissue disease. It is a form of lower extremity panniculitis, ^[3] an inflammation of the layer of fat under the epidermis.^[4]

Symptoms

Pain may be the first noticed symptom.^[3] People with lipodermatosclerosis have tapering of their legs above the ankles, forming a constricting band resembling an inverted coke bottle.^[3][5] In addition, there may be brownish-red pigmentation and induration.^[5]

Causes

The exact cause of lipodermatosclerosis is unknown.^[3][6] Venous disease, such as venous incompetence, venous hypertension, and body mass (obesity) may be relevant to the underlying pathogenesis.^[3]

Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries. Fibrotic tissue may predispose the tissue to ulceration. Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis. In advanced lipodermatosclerosis the proximal leg swells from chronic venous obstruction and the lower leg shrinks from chronic ulceration and fat necrosis resulting in the inverted coke bottle appearance of the lower leg.^[7]

Lipodermatosclerosis is most commonly diagnosed in middle-aged women.^[3]

Treatment

The management of lipodermatosclerosis may include treating venous insufficiency with leg elevation, elastic compression stockings, and bed rest; in some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibronolytic agents use an enzymatic action to help dissolve blood clots.^[3][4][5][8]
