Neonatal dermal erythropoiesis associated with severe rhesus immunization: amelioration by high-dose intravenous immunoglobulin

Late-onset blueberry muffin lesions following recombinant erythropoietin administration in a premature infant

Recombinant erythropoietin is being used in premature population for anemia of prematurity. It is considered very safe in this population, although risks are still being evaluated. We report the first case of dermal erythropoiesis as a side effect of recombinant erythropoietin in an extremely prematurely born infant presenting with late-onset blueberry muffin lesions.

Purpura in infants and children

Hemorrhage into the skin (purpura) may result from abnormalities in any of the three components of hemostasis: platelets, plasma coagulation factors, and blood vessels. The morphology, size, and distribution of the hemorrhagic lesions are helpful diagnostic features. The main causes of purpura in the newborn and the more common hemorrhagic disorders in children are reviewed.
