Cutaneous purpura is not necessarily leukemia. Cutaneous purpura is a condition in which the skin has subcutaneous bleeding, which means that blood leaks out of the blood vessels to the outside of the vessels, resulting in cutaneous purpura. Clinically, cutaneous purpura can be seen in a variety of diseases, including allergic purpura, immune thrombocytopenic purpura, and disorders of the coagulation system such as hemophilia a, hemophilia b, and vascular hemophilia. Patients with aplastic anemia also present with skin purpura, as do patients with leukemia. Leukemia is a malignant disease in which normal hematopoiesis is disrupted, thrombocytopenia and coagulation disorders occur in the peripheral blood, and skin purpura can also occur. But leukemia and skin purpura cannot be equated. In addition to bleeding, leukemia will definitely have a series of symptoms such as anemia and infection. So skin purpura may be one of the manifestations of leukemia, but it can’t be diagnosed as leukemia just because of skin purpura.
