title: [A case of ischemic colitis due to polyarteritis nodosa].
abstract: A 78-year-old female was admitted to our hospital with acute abdomen (abdominal pain and bloody stool). Abdominal examination revealed mild rebound tenderness on the right side. The laboratory data revealed severe inflammation (WBC: 33100/microliters, CRP:35.5 mg/dl). Panperitonitis was suspected because of diffuse and severe abdominal pain and rebound tenderness on the next day. X-ray examination by gastrografin showed mucosal irregularity and tubular narrowing of the tubular narrowing of the ascending colon which indicated ischemic colitis, and an emergency operation was performed. Histological examination of the pathologic specimens revealed fibrinoid necrosis and destruction of the internal lamina in small and medium-size arteries. We report a case diagnosed as ischemic colitis due to polyarteritis nodosa by the findings of its pathologic specimens.
