[Hereditary hemorragic telangiectasia and hepatic abcess].

We report the case of a 27-year-old man presenting with a hepatic abscess and hereditary hemorrhagic telangiectasia (HHT). The association between HHT and an infectious disease seemed to be induced by arteriovenous malformations and maybe also by a deficit of polymorphonuclear cells, a monocyte oxidative burst and phagocytosis. This diagnosis should be suggested in case of serious infections in young patients. Prevention is based on screening for and destroying infection, antibioprophylaxis and embolization of arteriovenous malformations.
