Heather Paladine, MD

A 51-year-old man is admitted to the hospital with painful ulcers on both lower extremities, severe anemia, and a 45-kg (100-lb) weight loss over the past year. Pain from the ulcers prevents him from walking. The ulcers developed about 5 years earlier, as a result of his wearing high boots for work; they began as small sores and grew over time.
