Small blood spots on the arm

The appearance of small blood spots on the arms may be caused by factors such as vascular nevus, purpura and low coagulation function.

1. Vascular nevus: Vascular nevus is also called capillary hemangioma. There are many small black spots on the arms. The most common consideration is that it may be caused by vascular nevus. It is mainly because there is a certain amount of capillary dilation in the superficial layer of the dermis of the skin, or capillary hyperplasia, which causes some capillary hemangiomas. If the symptoms are mild and have little impact on the skin, generally no special treatment is required. For patients who care more about their personal skin, laser surgery or freezing can be used to remove the cancer, which can ensure the removal effect and reduce damage to the skin.

2. Purpura: Suffering from purpura diseases will cause some small blood-like tissues to appear on the arms. This situation usually occurs in the lower limbs, especially the calves and ankles. It is more obvious. Severe cases will cause bruises to appear on the arms. Further testing is needed to clarify the diagnosis and provide appropriate treatment to prevent any impact on your health.

3. Low coagulation function: The skin tissue has not been injured, but small blood spots have appeared on the skin tissue. This may be caused by autologous coagulation dysfunction. You can go to a professional hospital to do coagulation function tests or blood routine tests to clarify.
