(MedPage Today) — A 70-year-old man went on a rare visit to his primary care physician complaining of some numbness and pain in his hand with difficulty fully opening his hand. When he showed the doctor, his palm appeared to have raised scars and the skin looked pulled together. He said he’d noticed some smooth nodules on the hand a couple of years ago, but he didn’t think much of it because he often worked with his hands. His thumb and index finger seemed unaffected. The doctor noted a long-term tobacco habit, and the patient said he had been in recovery from alcoholism for 3 years.
Can you diagnose the patient?
