A newborn baby has periods of erythema covering half of her face/head.
These periods of hemicephalic erythema occur on both sides of the face/head in the same baby. They can last a few seconds to a few minutes and then completely disappear! They can occur at any time but occur most commonly when the baby is lying down, on the dependent side of the head.
Diagnosis: Harlequin color change — unilateral transient hemifacial erythema in a newborn
Amazingly, this odd half-head, ephemeral flushing reaction has been reported to occur in 10 percent of all newborns. The reaction can last several seconds up to several minutes. The condition is harmless and is not a harbinger of any other health concerns. The condition usually appears in the first few days of life and almost always resolves within four weeks, if not sooner, without any additional appearances or complications. The condition can occur on both sides of the head in the same newborn, as it did in this patient.
The exact cause is uncertain but noted board-certified dermatologist, Neil Shah, MD, of Minnesota believes it is a result of a slightly immature autonomic nervous system that rapidly catches up in a few days or weeks after birth, resulting in a complete disappearance of the condition. No additional work-up is required.
