Acquired port-wine stains: A report of two cases and review of the literature

Abstract

Background: Acquired port-wine stains (APWS) are rare vascular malformations that share the same clinical and histological features as their congenital counterparts. Rare cases of AWPS secondary to trauma or in association with medications have been reported in the literature.

Patients and methods: We report two cases of APWS. One case appeared at the age of 2 months, the earliest reported in the literature and continued to evolve till the age of 3 years presenting with multifocal distribution mainly affecting the lower face. The second case developed during oral isotretinoin intake and persisted after discontinuation of the treatment.

Results and conclusions: The second patient declined treatment, but the first patient had a remarkable improvement following treatment with the pulsed dye laser, which remains the standard of care for capillary malformations on the face.

Keywords: facial port wine stain; isotretinoin; port-wine stain; pulsed laser.
