A 65-year-old white male resident of Rhode Island presented with a 5-month history of nonhealing ulcers on the posterior aspect of his neck. He denied any trauma to the area. He was in good physical health and had no systemic complaints. He was negative for human immunodeficiency virus, and his medical history was unremarkable, save for a short hospital admission for an "unexplained" pneumonia 4 years earlier. Six years ago, he lived in Arizona, where he was employed at a local hospital in the maintenance department and also worked as a landscaper.
