Idiopathic Symmetrical Peripheral Gangrene: A Rare Clinical Entity.

Symmetrical peripheral gangrene (SPG) is a rare disorder leading to ischemic necrosis of extremities. We present a rare case of idiopathic SPG in a 58-year-old male who did not seek any medical care, and history was elucidated only after he presented one year later for treatment of pneumonia. Extensive investigations revealed no etiology. SPG can result from a variety of conditions that cause disseminated intravascular coagulation and lead to distal hypoperfusion. The treatment is aimed at the control of the underlying disease and wound management.
