[Annular lesions following phototherapy in a newborn infant].

A 20-day-old girl was referred to our department for cutaneous lesions that appeared 1 week earlier and were not associated with any other symptoms (Figures 1 and 2). On the third day of life, the infant had presented jaundice and had been treated by phototherapy, which led to resolution of the symptoms within 48 hours. As relevant family history, the mother was currently being assessed for joint pain and leukopenia that had appeared during the pregnancy.
