Primary infection by Capnocytophaga canimorsus after dog bite is rare but may be difficult to identify and rapidly lethal. We describe a case of fatal septic shock with fulminant purpura occurred in a patient without specific risk factor two days after an irrelevant dog bite. The patient was brought to hospital because of altered mental status, fever, and abdominal pain. In a few hours patient became hypoxic and cyanotic. The patient became extremely hypotensive with shock refractory to an aggressive fluid resuscitation (40 ml/kg crystalloids). She received vasoactive drugs, antibiotic therapy, and blood purification treatment, but cardiac arrest unresponsive to resuscitation maneuvers occurred. Case description and literature review demonstrated that, also in patients without specific risk factors, signs of infection after dog bite should be never underestimated and should be treated with a prompt antibiotic therapy initiation even before occurrence of organ dysfunction.
