Thrombocytopenic purpura is a medical condition characterized by the sudden reduction of platelets in the blood, causing purple discolorations on the skin. While the term "thrombocytopenic purpura" is the official medical term used to describe this illness, there are a few synonyms that can be used interchangeably. Some of these include immune thrombocytopenia, idiopathic thrombocytopenic purpura, and immune-mediated thrombocytopenia. Regardless of the term used, the condition can cause serious health complications and must be treated promptly by a medical professional. Appropriate treatments may include steroids, immune globulin therapy, or even surgical removal of the spleen.
