Which disease is strongly linked to distal extremity ischemia in young male smokers?

• A. Wegener's granulomatosis
• B. Buerger disease
• C. Varicose veins
• D. Raynaud phenomenon

Answer: (B)

This item hinges on recognizing thromboangiitis obliterans, also known as Buerger disease. It is a segmental inflammatory vasculitis of small- to medium-sized arteries and veins in the extremities that typically affects young male smokers. The hallmark is distal ischemia of the fingers or toes, often with claudication, ulcers, or gangrene, and it is closely linked to tobacco use. The path features a thrombus that tends to be inflammatory and contains microabscesses with granulomatous inflammation, and the disease can involve adjacent veins and nerves. Importantly, stopping smoking can slow or halt progression, which is a key clinical clue. By contrast, Wegener’s granulomatosis involves granulomatous inflammation of the respiratory tract and kidneys, varicose veins cause venous insufficiency rather than arterial ischemia, and Raynaud phenomenon is a vasospastic color change disorder that does not classically drive distal digit ischemia with smoking-related onset in young men.
