This paper details the first case report of a patient with fulminant, gangrenous, ischemic colitis caused by polyarteritis nodosa which was successfully treated surgically.

Ischemic colitis is a rare complication of polyarteritis nodosa. It should be suspected in patients with a past history of polyarteritis nodosa who develop abdominal pain and rectal bleeding. The identification of cutaneous lesions preoperatively and or mesenteric or serosal vascular beading at operation are helpful in establishing this diagnosis. Prognosis is generally determined by the extent of systemic involvement by polyarteritis nodosa, and death is generally associated with renal failure.
