Harlequin syndrome is a condition characterized by autonomic dysfunction leading to hemifacial flushing on one side with pallor and impaired sweating on the other side. It is a rare condition that can be both congenital and acquired, with congenital cases being rarer, comprising ∼6% of all Harlequin syndrome cases. Harlequin syndrome is usually associated with other autonomic disturbances including Horner syndrome especially when presenting as a congenital condition. We reported the findings of a rare case of concomitant congenital Horner and Harlequin syndromes in an otherwise healthy 4-month-old male infant patient and provided a review of the current literature.
