Purpura fulminans is a rare disorder that causes severe bleeding and skin discoloration. The term "purpura" refers to the purple, bruise-like spots that appear on the skin, while "fulminans" indicates the sudden onset and rapid progression of the disease. While there are no exact synonyms for purpura fulminans, similar terms include disseminated intravascular coagulation (DIC), thrombotic thrombocytopenic purpura (TTP), and hemolytic uremic syndrome (HUS). These conditions are also characterized by abnormal blood clotting and bleeding, and may result in organ failure or death. Early diagnosis and treatment are essential in managing these conditions and improving outcomes for patients.
