What structural change is characteristic of lipodermatosclerosis?

1. Skin thickening

2. Increased elasticity

3. Decreased pigmentation

4. Loss of subcutaneous fat

The correct answer is: Skin thickening

Lipodermatosclerosis is characterized by a specific change in the skin's structure, which is the thickening of the skin. This condition often arises due to chronic venous insufficiency and is reflected in the skin's appearance and texture. The thickening is typically accompanied by other signs such as reddish-brown discoloration and fibrosis of the subcutaneous tissue. Understanding this condition is important as it indicates the progression of venous disease and helps in differentiating it from other disorders that may affect the lower extremities. The thickened skin is a protective response to underlying issues, signaling that a comprehensive approach to treatment must address the underlying venous insufficiency to manage the condition effectively. Other options, such as increased elasticity, decreased pigmentation, and loss of subcutaneous fat, do not accurately describe lipodermatosclerosis. While there may be variations in patient presentations, the hallmark of this condition remains the pronounced skin thickening.
