Primary biliary cirrhosis associated pustular vasculitis.

The association between primary biliary cirrhosis (PBC) and cutaneous vasculitides is well recognized. Pustular skin lesions though, have been described in association with hepatobiliary diseases other than PBC. Once the more common infective pustular rashes have been excluded, the differential diagnoses for a pustular skin rash are acute generalized exanthematous pustulosis (AGEP), Sweet's Syndrome (SS), pyoderma gangrenosum (PG) and pustular vasculitis(PV). We present a case of pustular vasculitis associated with PBC.
