Preterm infant with a late presentation of blueberry muffin lesions secondary to recombinant erythropoietin
Abstract
Our patient is a 26-week-old preterm female infant delivered by caesarean section secondary to severe maternal preeclampsia who had been receiving subcutaneous recombinant erythropoietin (r-EPO) for anemia of prematurity. At 8 weeks of age after 8 doses of r-EPO, the infant developed numerous non-blanching erythematous macules and patches located on the back, posterior shoulder, and posterior arms, concerning for late-onset blueberry muffin lesions. Biopsy of the lesions confirmed dermal hematopoiesis. After r-EPO was discontinued all skin lesions gradually resolved over a period of 2 weeks and never recurred.
