Harlequin syndrome, which is a rare disorder caused by dysfunction of the autonomic system, manifests as asymmetric facial flushing and sweating in response to heat, exercise, or emotional factors. The syndrome may be primary (idiopathic) with a benign course, or can occur secondary to structural abnormalities or iatrogenic factors. The precise mechanism underlying idiopathic harlequin syndrome remains unclear. Here, we describe a case of a 6-year-old boy who reported left hemifacial flushing and sweating after exercise. He had an unremarkable birth history and no significant medical history. Complete ophthalmological and neurological examinations were performed, and no other abnormalities were identified. Magnetic resonance imaging was performed to exclude lesions of the cerebrum and cervicothoracic spinal cord, and no abnormalities were noted. His final diagnosis was classic idiopathic harlequin syndrome. Herein, we report the first pediatric case of idiopathic harlequin syndrome in Korea.

Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass.

Purpose: We report a patient with DiGeorge syndrome who was later diagnosed as mild metopic synostosis and received anterior 2/3 calvarial remodeling. Methods: A 16-month-old boy, who underwent palatoplasty for cleft palate at Chungnam National University Hospital when he was 12 months old of age, visited St. Mary's Hospital for known DiGeorge syndrome with craniosynostosis. He had growth retardation and was also diagnosed with hydronephrosis and thymic agenesis. His chromosomal study showed microdeletion of 22q11.2. On physical examination, there were parieto-occipital protrusion and bifrontotemporal narrowing. The facial bone computed tomography showed premature closure of metopic suture, orbital harlequin sign and decreased anterior cranial volume. The interorbital distance was decreased (17 mm) and the cephalic index was 93%. Results: After the correction of metopic synostosis by anterior 2/3 calvarial remodeling, the anterior cranial volume expanded with increased interorbital distance and decreased cephalic index. Fever and pancytopenia were noted at 1 month after the operation, and he was diagnosed as hemophagocytic lymphohistiocytosis by bone marrow study. He however, recovered after pediatric treatment. There was no other complication during the 12 month follow up period. Conclusion: This case presents with a rare combination of DiGeorge syndrome and metopic synostosis. When a child is diagnosed with DiGeorge syndrome soon after the birth, clinicians should keep in mind the possibility of an accompanying craniosynostosis. Other possible comorbidities should also be evaluated before the correction of craniosynostosis in patients as DiGeorge syndrome. In addition, postoperative management requires a thorough follow up by a multidisciplinary team of plastic surgeons, neurosurgeons, ophthalmologists and pediatricians.
