This patient suffers from scleroderma complicated by Raynaud phenomenon. The latter refers to intermittent, bilateral attacks of vasospasm of the fingers or toes (sometimes affecting the ears or nose), resulting in pallor, paresthesias, and pain from ischemia. The symptoms are precipitated by cold or emotional stimuli and relieved by heat. Raynaud phenomenon may occur as an isolated disorder or as a feature of a number of systemic diseases, including systemic lupus erythematosus and scleroderma. Intermittent claudication (choice C) is associated with peripheral vascular disease (atherosclerosis). Chilblains (choice A) represent itchy or tender red or purple bumps that occur as a reaction to cold.Diagnosis: Scleroderma
