title: A case of hydroa vacciniforme.
abstract: Hydroa vacciniforme (HV) is a rare and chronic pediatric disorder that is characterized by photosensitivity and recurrent vesicles that heal with vacciniforme scarring. The pathogenesis of HV is unknown; no chromosome abnormality has been identified. HV patients have no abnormal laboratory results, so the diagnosis of HV is based on identifying the associated histological findings in a biopsy specimen and using repetitive ultraviolet phototesting to reproduce the characteristic vesicles on a patient's skin. Herein, we present a case of HV in a 7-year-old female who was diagnosed with HV according to histopathology and ultraviolet phototesting.
