title: Twin transfusion syndrome causing cutaneous erythropoiesis.
abstract: Two cases of twin transfusion syndrome are described in which the donor twin exhibited blueberry muffin-like macules and papules associated with cutaneous erythropoiesis. No evidence was found in either case for intrauterine viral infection, the most common cause of cutaneous erythropoiesis. Cutaneous erythropoiesis is these two cases is considered to be due to persistence or reactivation of fetal dermal erythropoiesis secondary to prolonged, severe intrauterine anemia.
