A case of acquired port wine stain: an association with repeated sunburn?

BACKGROUND: Unlike congenital port wine stain (PWS), an acquired PWS is a rare vascular lesion that develops later in life. Although solar damage is associated with acquired PWS, there is no reported case of acquired PWS after sunburn in the literature.

METHODS: We report a case of a 54-year-old man diagnosed with acquired PWS possibly caused by repeated sunburn.

RESULTS: We recommended laser treatment to our patient; however, the patient did not chose to receive any treatment.

CONCLUSIONS: Our case demonstrates a possible rare occurrence of an acquired PWS after sunburn with larger lesions and more diffuse distribution. For this reason, our case differs from other acquired PWS cases.
