Púrpura fulminans asociada a déficit adquirido de proteína S en una paciente con neumonía por Streptococcus pneumoniae

Purpura fulminans is a hematological emergency characterized by cutaneous necrosis and laboratory disseminated intravascular coagulation (DIC) parameters. It can appear associated with severe infections, as an autoimmune process after benign infections in childhood or be the presenting symptom of a congenital protein C or S deficiency. A clinical case of purpura fulminans associated with acquired protein S deficiency is described in a 6-year-old patient with severe Streptococcus Pneumoniae pneumonia.
