Extramedullary hematopoiesis secondary to COVID-19: A first case report in a newborn.

A 39 weeks newborn baby was born with blueberry muffin macules and papules on her back. Skin biopsy was performed and showed extramedullary hematopoiesis. The mother who was infected by COVID-19 infection at 35 weeks of pregnancy did not have any other risk factor for extramedullary hematopoiesis, thus making this viral infection the most likely cause of blueberry muffin rash.
