To the Editor:
The term "Harlequin syndrome" was introduced by Lance et al. (1) to describe a rare autonomic dysfunction characterized by hemifacial sweating and flushing. The syndrome may be triggered by thermal, gustatory, emotional, or exertional stimuli and may also be found in conjunction with Horners syndrome (1-3). Ocular findings in Horners are associated with lesions at the level of T1, whereas sudomotor and vasomotor findings of Harlequin syndrome are thought to be associated with the level of T2 and T3 (3,4). In the perioperative setting, Harlequin syndrome has been reported postoperatively after the resection of a neck mass as well as after internal jugular venous catheter placement (5,6). It is thought that interrupted sympathetic outflow results in an ipsilateral flushing and sweating defect. We report a case of Harlequin syndrome in a 77-yr-old female during pancreatic surgery that resolved spontaneously on emergence from general anesthesia (Fig. 1). The patient had no prior autonomic dysfunction and reported no postoperative events. An asymmetrical epidural block demonstrated preoperatively (T2 on left, T4 on right) was suspected as the cause, but the etiology remains unclear. This is the first report of intraoperative Harlequin syndrome.
