Medical Challenge - What's the Diagnosis?

The New England Journal of Medicine diagnostic challenge is aimed at physicians but anyone can play. This patient has skin lesions (click on image for a better view) that are non-tender, non-itchy and slowly growing. What lab test would cinch the diagnosis?
1. 17-hydroxyprogesterone
2. Angiotensin-converting enzyme
3. Anti-tissue transglutaminase antibody
4. Prolactin
5. Vitamin B6
The answer will be posed on Friday.
