title: A Case of Undiagnosed Harlequin Syndrome Presenting in General Dental Practice.
abstract: Harlequin syndrome is a rare, clinically striking syndrome characterized by distinctly demarcated asymmetric facial flushing and sweating. It may be of idiopathic aetiology or caused by demonstrable ipsilateral damage to the sympathetic nervous system. A case is described where a patient presented to her general dental practitioner complaining of distinctly demarcated unilateral facial flushing and sweating. Onward referral resulted in a diagnosis of Harlequin syndrome. CPD/CLINICAL RELEVANCE: This article highlights the neurological signs and symptoms of Harlequin syndrome, making it easier to recognize if it presents in general dental practice.
