Buerger's disease is commonly found in which population and presents with what symptom?

• A. Female Non-Smokers With Arms Pain
• B. Elderly With Chest Pain
• C. Male Smokers With Feet Pain
• D. Children With Leg Pain

Answer: (C)

Buerger's disease (thromboangiitis obliterans) is strongly linked to tobacco use and tends to affect younger men. It causes inflammation and occlusion of small- and medium-sized arteries in the distal limbs, leading to ischemic pain in the hands and feet, often with claudication and, as it progresses, ulcers or gangrene. This makes the description of a male smoker with feet pain the best fit. The other options don’t match the typical patient profile or the common location of symptoms (for example, chest pain points toward cardiac disease, and children or non-smokers are not the usual demographic for this condition).
