Photo Quiz. Reaction After Smallpox Vaccination

摘要

A 31-year-old woman presented with a 12-hour history of pain, tenderness, swelling, and erythema over her left anterior chest wall nine days after receiving a primary smallpox vaccination. As instructed, she kept the site loosely covered with dry gauze and an adhesive dressing and made daily dressing changes. Two days before presentation, she experienced neck and supraclavicular pain on the left side that resolved within 24 hours. She had not missed work, although discomfort at the site during the previous 12 hours made it difficult for her to sleep.
