Spontaneous liver rupture as first sign of polyarteritis nodosa.

Polyarteritis nodosa (PAN) is one of the systemic vasculitis that affects the media wall of arteries of small and medium diameter. Diagnosis proves difficult due to the unspecific symptoms that dominate the clinical profile. Liver involvement is very diverse, ranging from the development of cirrhotic liver disease to acute abdomen presentation that requires surgery because of liver rupture. The management of these patients requires an expert multidisciplinary team. There are several cases in the literature that describe a sudden liver rupture as the first manifestation of a PAN. In this paper we present the case of a 75 years old patient without any previous disease, who is subjected to major hepatic resection for spontaneous liver rupture.
