• Resumen

  • We report a 37 years old male with a dermatomyositis treated with oral cyclophosphamide. He was admitted to the hospital due to a zone of skin necrosis with purulent exudate, located in the second left toe. A complete blood count showed a leukocyte count of 2,600 cells/mm³. A Chest CAT scan showed a pneumomediastinum with emphysema of adjacent soft tissue. Cyclophosphamide was discontinued and leukocyte count improved. The affected toe was amputated and a chest CAT scan showed a partial resolution of the pneumomediastinum. We discuss and review the pathogenesis, clinical presentation and management of pneumomediastinum and cutaneous necrosis in association with dermatomyositis.
