Purpura is possible to be cured. Purpura refers to subcutaneous bleeding foci on the skin with a diameter of 3~5mm. Skin purpura can occur when there is a severe reduction in platelet count and/or coagulation dysfunction, and subcutaneous bleeding can be stopped and gradually absorbed after elevating the platelet count and correcting the coagulation dysfunction. Idiopathic thrombocytopenic purpura (primary immune thrombocytopenia), allergic purpura and other diseases are common causes of skin purpura and need to be treated by specialists. For example, patients with primary immune thrombocytopenia may be cured after treatment with drugs such as prednisone and gammaglobulin, but some of them may relapse again. Patients with skin purpura need to go to the hematology department in a timely manner to clarify the cause of skin purpura and then treat the cause under the guidance of a physician.
