Which condition is most associated with brown discoloration and thickened skin of the legs?

• A. Venous insufficiency
• B. Arterial insufficiency
• C. DVT
• D. Lymphedema

Answer: (A)

Chronic venous insufficiency leads to venous hypertension and stasis, which causes leakage of red blood cells into the skin and subsequent hemosiderin deposition. This pigment change gives a brown or bronze discoloration, and ongoing inflammation with fibrosis produces thickened, leathery skin known as lipodermatosclerosis. Together, these skin findings are classic signs of venous disease and explain why brown discoloration with thickened skin on the legs points to venous insufficiency. Arterial insufficiency would more often present with pallor, coolness, thin and shiny skin, hair loss, and pain on exertion rather than brown staining. A DVT typically presents with acute unilateral leg swelling, warmth, and tenderness rather than chronic pigment change and skin thickening. Lymphedema involves swelling from lymphatic obstruction and can cause skin thickening, but brown discoloration is not the hallmark feature here.
