Scrotal skin capillary bleeding is most often seen with trauma or blood disorders.
The scrotal skin is more fragile and tends to rupture and bleed after unconscious friction or scratching, and if there has been itching before the bleeding, then scratching and bleeding is very likely. The first thing you need to do is to pay attention to local hygiene. You can disinfect it with iodine and cover it with gauze to prevent secondary damage and infection. If the damage is more serious or bleeding, it is recommended to go to a regular hospital for emergency treatment immediately.
If bleeding due to trauma is ruled out, the possibility of hematologic disease needs to be considered. The bleeding can be classified according to the amount and area of bleeding: blebs (less than 2 mm in diameter), purpura (3-5 mm in diameter), petechiae (more than 5 mm in diameter), and if the blood leaks out of the blood vessels and causes a skin elevation called a hematoma. And subcutaneous capillary bleeding can be seen in: thrombocytopenic purpura, hemophilia, leukemia, etc.
