[Periarteritis nodosa of the gallbladder--2. Surgical case reports].

P.n. of the gallbladder is discussed as isolated and systemic form according to the description and analysis of 2 cases. In the 1st case the disease remained restricted to the gallbladder and no further complications involving the vessel system appeared so far in the follow up (2 years). In the 2nd case the patient dies few days after the operation due to a systemic involvement. Literature survey reveals a nonuniform classification of angiitis. Nevertheless we have tried to assign (classify) to 2 above mentioned cases.
