Question 4 of 5
Port-wine stains do not enlarge after birth; any apparent increase in size is caused by growth of the child. Facial lesions are the most common. They are pinkred, sharply demarcated macules and patches in infancy; with time, they darken to a purple or port-wine color. Vascular blebs may form within the lesions and become symptomatic or bleed. The most successful treatment modality in use is the pulsed dye laser, which can result in 80 % to 90 % improvement. Treatment is more effective if undertaken in infancy.
Correct Answer: A
Rationale: Port-wine stains are congenital capillary malformations that persist lifelong. Their apparent growth is due to the child's growth, not lesion expansion. Pulsed dye laser is the gold standard treatment, especially effective early in life.
