Vascular birthmarks are a broad term that encompasses any abnormal development of blood vessels in the skin or internal organs. These conditions can range from mild to severe, depending on the individual case. Vascular anomalies are usually present at birth and may be present for life, though they can often be managed with treatments such as laser therapy or medical interventions.
Types of Vascular Birthmarks
The most common type of vascular birthmark is known as a port-wine stain or capillary malformation. This condition appears as a flat, red-purple mark on the skin that is caused by an overgrowth of dilated capillaries, which are small blood vessels located just below the surface of the skin. Port-wine stains can occur anywhere on the body but are most commonly found on the face, neck, arms, legs, and trunk. They tend to appear darker in color when exposed to cold temperatures.
Vascular lesions can also develop internally in organs such as the liver or brain and can have more serious consequences than those seen externally in port-wine stains or hemangiomas. Diagnosis of these conditions requires an extensive physical exam as well as imaging studies such as CT scans and MRIs to properly assess their size and location within the body’s structures. Treatment for these conditions depends upon their severity; some require no intervention, while others may need surgical removal or radiation therapy if medical treatment has proven ineffective.
Regardless of what type of vascular anomaly is present, it is important for patients to understand that treatment options exist that can help reduce their appearance or alleviate any underlying symptoms they may be experiencing due to changes in endothelial cells – cells that line our blood vessels – caused by these debilitating conditions.
