Spontaneous skin necrosis revealing protein S deficiency in Crohn's disease

Inflammatory bowel diseases are associated with a state of hypercoagulability secondary to several mechanisms, protein S deficiency being one of these. It can be revealed by spontaneous skin necrosis in children. This condition is rare in adults with Crohn's disease. We are reporting a case of a 35-year-old woman with active Crohn's disease who presented a protein S deficiency responsible for an extensive spontaneous skin necrosis. The evolution was favourable after vascular filling, curative anticoagulation, antibiotic therapy, as well as a high-dose of corticosteroid therapy. We are reporting this case in order to emphasize the importance of considering skin necrosis as a possible cutaneous manifestation of inflammatory bowel diseases.
