Acquired port-wine stains in six pediatric patients

Port-wine stains, also known as capillary malformations, are due to dermal vascular ectasia and dilation and are most commonly congenital; however, acquired port-wine stains (APWS) developing later in life have been noted in the literature, most commonly in the context of trauma.

This case series presents 6 pediatric patients with APWS who first developed lesions between ages 3 and 11 years in the absence of a traumatic or other etiologic trigger.

The epidemiology, clinical features, and treatment response of these patients are compared to what has been previously described in other cases in the literature.
