The patient is a 72-year-old woman who complains of multiple skin lesions on her lower legs. She says she first noticed them several months ago, appearing in a net-like pattern, then becoming painful ulcerations, and finally leaving atrophic scars. She is concerned because she had already had several bouts of deep vein thrombosis.
