Harlequin color change is a phenomenon observed in some newborns, characterized by a dramatic change in skin color. Specifically, it refers to a transient condition where the skin on one side of the body will become red while the other side remains pale, particularly when the infant is positioned or exposed to stimuli. This condition is not due to any underlying pathological processes but is often related to the immaturity of the autonomic nervous system in newborns.

The association with capillary hemangioma is notable because this type of vascular birthmark is common in infants and can present with various color changes and characteristics. However, harlequin color change itself is more about the physiological response in infants rather than a sign of a hemangioma. While capillary hemangiomas are benign and often do not require treatment unless they interfere with function or cause cosmetic concerns, harlequin color change is generally a benign and self-limiting condition.

Other conditions, such as cutis marmorata, vasculitic rash, and infantile eczema, manifest different symptoms and often indicate specific medical concerns or conditions that do not overlap with the characteristics of harlequin color change. Thus, recognizing harlequin color change as a distinct, physiological response helps clarify why cap
