Warren White, MD

This rash, which covered a 68-year-old woman's body, was noted to have worsened during the past 2 months. A cephalosporin antibiotic had failed to clear the condition. The patient, a nursing home resident, suffered from emphysema, asthma, and heart disease. She had been receiving oxygen therapy and prednisone for 1 year.

The patient reported that he had noticed the facial eruption a couple of months earlier. On examination, the lesion appeared more plaque-like and dense than is typical of rosacea. The differential diagnosis included lupus, mycosis fungoides, rosacea, and angiosarcoma.
