Neonatal Mastauxe (Breast Enlargement of the Newborn)

Abstract

Neonatal Mastauxe (NM) represents a common, well known and physiologic condition that requires simple observation and parental reassurance. "Giant" NM (exceeding 3 cm of diameter) is an infrequent clinical picture, potentially mimicking a bacterial infection. Being aware of this clinical entity and (in dubious cases) performing blood tests and/or ultrasound investigation may help clinicians in making the correct diagnosis and permits parental reassurance on one hand, and to avoid unnecessary therapies on the other hand.
