Abstract
Hydroa vacciniforme is a rare, idiopathic, chronic photodermatosis that usually begins in childhood and resolves spontaneously in early adulthood. It is characterized by appearance of vesicles on sun-exposed areas. The vesicles crust and heal within one to six weeks, leaving vacciniform/varioliform scars. We report an 11-year-old boy with a 5-year history of recurrent blisters on sun-exposed areas that deteriorated each summer. He was treated with antimalarials, topical photoprotective agents, sun avoidance, dietary fish oil and supplementary doses of vitamin D3. Strict adherence to the regimen resulted in remission.
