If red blood spots appear on the body, which do not protrude from the surface of the skin, but fade with light pressure, consider them bleeding spots. For bleeding dots, the first thing to consider is to exclude vascular diseases, platelet abnormalities, and deficiencies of coagulation factors. For example, vascular diseases such as allergic purpura or vitamin E deficiency may lead to increased permeability of the blood vessel walls, and in addition to bleeding dots, there is a possibility of involvement of other internal organs and organs, abdominal pain, joint pain, hematuria, and proteinuria. In addition, low platelet count and functional decline can also lead to bleeding, often seen in aplastic anemia or acute leukemia. In addition, deficiencies in clotting factors, such as in liver lesions, can also cause blood to clot less easily after rupture of blood vessels in the skin, resulting in petechiae.
