Purpuric Phototherapy-induced Eruption in Transfused Neonates: Relation to Transient Porphyrinemia

Abstract

The distribution of the eruption in areas exposed to light and presence of circulating porphyrins suggest that porphyrinemia may underlie the light-induced purpuric eruption. Additional studies will be required to determine definitively the mechanisms of both the purpuric phototherapy-induced eruption and the development of increased blood porphyrin levels in these transfused neonates.
