Abstract
Background: The available literature on intrauterine transfusion focuses largely on its application in fetal alloimmunization rather than hereditary red cell disorders, with limited illustration of its associated histopathologic findings. Case report: We present the histologic findings in a placenta associated with preterm delivery of an infant with autosomal SPTA1 mutation following multiple intrauterine transfusions, including appropriate villous maturation, subchorionic organizing hematomas, hemosiderin-laden macrophages, and dysmorphic fetal erythrocytes within villous capillaries. Conclusion: Intrauterine transfusion is associated with placental histologic findings that reflect procedural changes without significant disruption of placental membranes or villous maturation.
