A Caucasian girl, born to a gravida 2, para 2-0-0-2 mother, presented two days after birth with an erythematous, scaly, atrophic rash primarily in the periorbital region but also on her back.

The mother first reported no past medical history but admitted to photosensitivity on further questioning; she reported no joint pains.
