Abstract
Degos' disease, otherwise known as "malignant atrophic papulosis" is a rare vasculopathy with an unknown etiology characterized by typical cutaneous lesions. Involvement of the gastrointestinal (GI) tract is observed in approximately half of patients and small infarctions in the mucosa can cause perforation and resulting peritonitis, the leading cause of death. We present a fatal case of Degos' disease with skin and GI involvement, manifesting as recurrent intestinal perforations and peritonitis, in a 15-year-old Iranian boy.
