Case report describes acquired port-wine stain presenting with dilated dermal capillaries, highlighting clinical and histopathological differentiation from other vascular malformations.
Port-wine stain (PWS) are vascular malformations characterised by dilated dermal capillaries with normal endothelial cells. Congenital PWS are the most prevalent vascular malformation affecting 0.3–1% of newborns while acquired PWS (APWS), though an uncommon entity, exhibit morphological and histological similarity to congenital PWS. We hereby report a case of APWS along with a comprehensive comparison of clinical, histopathological and dermoscopic findings of other acquired vascular malformations.
