Vascular birthmarks are red, dark red, or pink spots or patches on the skin that may be present at birth or shortly after birth. Vascular birthmarks are caused by abnormalities in blood vessel formation during pregnancy, such as excessive blood vessel formation or the formation of blood vessels that are more dilated than normal.
Birthmarks are a type of skin abnormality. The appearance, shape or color may vary depending on the abnormality of cells such as skin cells, blood vessels, lymphatic channels. Red birthmarks are one of the characteristics of birthmarks that usually do not cause harm to the body. Moreover, red birthmarks may fade on their own or may be treated to be better by various methods such as laser skin resurfacing or using various medications.
Causes of red birthmarks
Birthmarks may appear due to abnormalities in the blood vessels under the skin, such as excessive blood vessel formation or blood vessels that dilate more than normal. Birthmarks can be divided into 3 types as follows:
- Salmon patch is a red birthmark caused by dilated blood vessels under the skin. There may be increased blood flow in the area, which may result in this type of birthmark.
- Hemangioma: This type of birthmark is caused by a large number of blood vessels coming together and pushing against the skin, forming a lump.
- Port-Wine Stain: This type of birthmark may occur due to abnormalities in the formation of capillaries under the skin. The capillaries may dilate abnormally, resulting in a port-wine stain.
However, the cause of the abnormality in blood vessel formation is still unclear. The formation of nevus may not be related to genetics or abnormalities that occur during pregnancy.
Symptoms of red birthmarks
