[Necrosis of maxilla secondary to purpura fulminans. A case report].

Purpura fulminans in infants is a rare, life-threatening condition mostly due to Neisseria meningitides. The condition is often fatal unless there is early recognition of the clinical symptoms, prompt diagnosis, and judicious replacement therapy. We observed a case of maxilla necrosis in a 5-month-old infant due to purpura fulminans. An acute necrotic process affecting the maxilla with denudation of bone and spontaneous exfoliation of teeth was noted. After 2 months, the patient was free of symptoms. To our knowledge, this is the first case report of necrosis of the maxilla secondary to a purpura fulminans. Prompt diagnosis and prompt medical intervention are necessary to avoid such complications.
