The Harlequin syndrome is an idiopathic, autonomic disorder. It typically presents with unilateral sweating and flushing of the face. It could be caused not only by autonomic dysfunction or space-occupying central neuropathy, but by some clinical interventions as well. Although iatrogenic Harlequin syndrome is rare, clinicians should be aware of this condition to diagnose correctly and provide suitable assistance.
