title: Acquired port-wine stain.
abstract: The development of a capillary hemangioma in adult life is an unusual event. These lesions normally occur as congenital cutaneous nevi. We describe the history and histologic findings in a man who developed such a lesion after a cricket ball injury to the right cheek at age 46 years. The literature on acquired port-wine stain is reviewed. Discussion is centered on whether there are factors predisposing to this response to injury and whether damage to autonomic nerves is important.
