title: Gallbladder vasculitis.
abstract: Five cases of gallbladder vasculitis were encountered during a 10-year period in a community hospital with annual surgical cases of about 12,000. All five patients were clinically diagnosed as having cholelithiasis with or suspected to have cholecystitis. Vasculitis in the form of arteritis identical to that seen in polyarteritis nodosa was present microscopically in the cholecystectomy specimens. One patient presented with systemic symptoms, and the diagnosis of polyarteritis nodosa was established after arteritic lesions were identified in the cholecystectomy, liver biopsy, and appendectomy specimens. In another patient, the diagnosis of polyarteritis nodosa was established after a retrospective identification of one additional site of arteritis in the appendix removed 5 years prior to cholecystectomy. In another, gallbladder vasculitis was associated with scleroderma; the patient was studied thoroughly at autopsy shortly after cholecystectomy, and no evidence of polyarteritis nodosa was found. In the last two, gallbladder vasculitis was not associated with systemic diseases.
