Rare autoimmune disease that causes bruising

When you cut or injure yourself, your body uses special cells, called platelets, and other chemicals, called clotting factors, to form a blood clot and control your bleeding. Bleeding disorders sometimes occur when the platelets or clotting factors are not working properly and do not form clots. Bleeding or clotting disorders include:

  • Disseminated intravascular coagulation (DIC), a condition that comes on quickly. Small blood clots form and move through the bloodstream, blocking small blood vessels and using up the clotting factors that are needed to stop bleeding. Emergency treatment is needed to stop bleeding and save the person's life.
  • Idiopathic thrombocytopenic purpura (, also known as primary or autoimmune thrombocytopenic purpura), a disorder in which a low platelet count causes abnormal bleeding. The cause of ITP in adults is not known. In children, ITP may be an that is triggered by a viral infection.

  • Hemolytic uremic syndrome, a serious and often fatal disorder in which the number of platelets suddenly drops, red blood cells are destroyed, and the stop working. The cause is not known, but the syndrome may be triggered by a bacterial infection or medicine use.
  • Henoch-Schonlein purpura, also known as allergic purpura, an inflammatory disease of the small blood vessels that most often affects children. The cause is not known, but it may be the result of an or a severe . Symptoms may include sudden , fever, loss of appetite, abdominal cramping, , and bruising.
