A 41-year-old man who had immigrated to the United States from Costa Rica 10 years prior presented with a 2-year history of tingling and pain in his hands and feet. He had no other symptoms and reported taking no medications. Findings on skin examination included near-complete loss of eyebrows and eyelashes, a scaly plaque on the right shin, and mild bilateral erythema of the earlobes, distal fingers, and toes (Figure). He also had right axillary and bilateral inguinal lymphadenopathy.
