There are two blood-red spots on the glans

It is not an allergic rash. The characteristics of the rash are that it is higher than the skin, fades when pressed, and it itches. Therefore, it should be considered as blood spots. The appearance of small blood spots or ecchymosis on the skin often reminds that the blood circulation function has changed abnormally. The blood circulation function of the body is coordinated by blood vessels, platelets and coagulation factors. Any change in any one of them can cause bleeding.

Diseases that cause skin bleeding spots include:

1. Vascular diseases:

Such as vitamin C deficiency (scurvy);

Allergic purpura is a hypersensitivity inflammation of the capillaries, which increases the wall thickness and permeability. It not only causes skin hemorrhages and edema, but can also invade other internal organs and organs of the body, causing abdominal pain, joint pain, hematuria, proteinuria, etc.

Some infectious diseases, such as influenza hemorrhagic fever, septicemia, hypoxia and poisoning, can also damage the capillary wall, increase its permeability, and allow red blood cells to enter from the gaps in the wall, which can also increase the elasticity of the capillary and make it easy to rupture. These conditions can also cause bleeding.

2. Platelet abnormalities:

Too few platelets and weakened platelet function can also cause bleeding, which is common in aplastic anemia, acute leukemia, idiopathic thrombocytopenic purpura, and secondary thrombocytopenic purpura.

3. Lack of coagulation factors:

When clotting factors are deficient, blood will not coagulate easily after blood vessels in the skin rupture, resulting in bruises. This is because most clotting factors are produced in the liver and need to be maintained.
