Blueberry Muffin Baby: Differentials   Leave a comment

Generalised non-blanching, blue-red macules or firm dome-shaped papules on a neonate’s skin, mostly over the head, neck, trunk: a sign of extramedullary dermal haematopoiesis persisting beyond what normally occurs up to the fifth month of gestation. In the strictest sense the term describes the appearance of congenital TORCH infections; but nowadays may also refer to similar lesions in some haematologic dyscrasias and vascular malformations.
