Isolated necrotizing panarteritis of the gallbladder. Case report.

Two cases of isolated gallbladder involvement by necrotizing panarteritis histologically resembling classic polyarteritis nodosa are reported and the literature is reviewed. No reports suggest that isolated gallbladder involvement may evolve to systemic ('classic') polyarteritis nodosa. Finding of necrotizing panarteritis in the gallbladder without clinical evidence of systemic/multiorgan disease does not warrant extensive investigations.
