Blueberry muffin baby is a term used to describe the characteristic distributed purpura due to extramedullary hematopoiesis found in infants.:826 It was originally considered characteristic of rubella, but is now considered to be potentially associated with many other conditions, such as cytomegalovirus and metastatic neuroblastoma.

The TORCH infections can lead to severe fetal anomalies or even fetal loss. They are a group of viral, bacterial, and protozoan infections that gain access to the fetal bloodstream transplacentally via the chorionic villi. Hematogenous transmission may occur at any time during gestation or occasionally at the time of delivery via maternal-to-fetal transfusion.
