A birthmark formed by blood vessels that is often present at birth is called:

• A. Capillary hemangioma
• B. Albinism
• C. Alopecia
• D. Anhidrosis

Answer: (A)

Vascular birthmarks are caused by an overgrowth or dilation of blood vessels in the skin. A capillary hemangioma is a benign proliferation of capillaries that forms a red or pink birthmark, often present at birth or appearing soon after. It’s commonly called a strawberry birthmark and may grow during infancy before gradually fading over time. The other terms describe different conditions: albinism is a pigment deficiency causing very light skin and hair; alopecia is hair loss; anhidrosis is the absence of sweating. So, the birthmark formed by blood vessels is capillary hemangioma.
