What is the typical skin discoloration associated with chronic venous insufficiency?

The typical skin discoloration associated with chronic venous insufficiency is a rusty-brown color. This discoloration occurs due to the accumulation of hemosiderin, a pigment that results from the breakdown of red blood cells that leak into the surrounding tissue due to increased venous pressure. Over time, the body attempts to manage this leakage, which leads to the brownish pigmentation as the hemosiderin is deposited in the skin and subcutaneous tissues.

This rusty-brown coloration is especially noticeable around the ankles and lower legs, areas most affected by poor venous return. Recognizing this skin change is crucial for clinicians, as it can assist in diagnosing chronic venous insufficiency and distinguishing it from other conditions with similar symptoms. The other choices, such as a yellow tint or red patches, are not characteristic of chronic venous insufficiency and may indicate other skin or circulatory issues, while pale skin would usually suggest compromised blood flow rather than the resulting discoloration from chronic venous problems.
