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 surgic...

The patient was asymptomatic, and the tumor was incidentally diagnosed on abdominal ultrasonography. A subsequent computed tomography (CT) of the abdomen confirmed a 12 x 7 x 8-cm homogenous mass of the right adrenal. Magnetic resonance imaging (MRI) showed a solid mass measuring 13 x 7...

Mediastinal ganglioneuroma with perineural cell differentiation. Report of a case.
