Adult-onset acquired port-wine stain in the absence of trauma: A case report

Port-wine stains (PWS), currently termed port-wine capillary malformations (PWCMs) according to the International Society for the Study of Vascular Anomalies classification, are congenital capillary malformations that present at birth as a pink-to-red patch that darkens over time.1,2 In contrast, acquired PWS or adult-onset PWS occur later in life. Trauma has been the most commonly reported trigger and is often described under the term Fegeler syndrome.3 Acquired PWS is a rare and infrequently reported condition, with a limited number of cases reported in the literature.
