title: Multifocal stenosing ulcerations of the small intestine revealing vasculitis associated with C2 deficiency.
abstract: A patient with cryptogenic multifocal ulcerous stenosing enteritis characterized by repeated bouts of intestinal obstruction, ulcerative stenosis of the small bowel relapsing after surgical resection, and steroid sensitivity is described. Fourteen strictures of the jejunum were found at laparotomy. Despite resection, abdominal pain persisted. Steroid therapy was effective but led to dependence. In our patient, cryptogenic multifocal ulcerous stenosing enteritis was associated with fever, asthma, Raynaud's phenomenon, sicca syndrome, heterozygous type I C2 deficiency (28-base pair gene deletion), stenosis, and aneurysms in selective mesenteric angiography. It is hypothesized that cryptogenic multifocal ulcerous stenosing enteritis might be related to a particular form of polyarteritis nodosa with mainly intestinal expression or to a yet unclassified independent vasculitis.
