There are two blood red spots on the glans penis

It is not an allergic rash. The characteristics of the rash are that it is higher than the skin, fades when pressed, and feels itchy. Therefore should be considered as blood spots. The appearance of small blood spots or petechiae on the skin often indicates abnormal changes in blood circulation function. The blood-activating effect of the body is coordinated by blood vessels, platelets and coagulation factors. Disease on either side can cause bleeding.

Conditions that cause bleeding spots on the skin include:

1. Vascular diseases:

Such as vitamin C deficiency (scurvy)；

Henoch-Schonlein purpura - is a hypersensitive inflammation of the capillaries, which increases the permeability of the wall. It not only causes skin bleeding spots and edema, but can also invade other internal organs and human organs, 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 cause red blood cells to be discharged from the wall gap. They can also increase the flexibility of the capillary and make it easy to rupture. This condition can cause bleeding.

2. Abnormalities in platelets:

Too few platelets and decreased function can also cause bleeding. Commonly seen in aplastic anemia, acute leukemia, idiopathic thrombocytopenic purpura, secondary thrombocytopenic purpura, etc.

3. Lack of coagulation factors:

When coagulation factors are deficient, blood will not easily clot after the skin blood vessels rupture, resulting in petechiae. Because most coagulation factors are produced by the liver and require vitamin B
