2 Fig 1 The barium swallow revealed a smooth filling defect in the middle and lower thoracic esophagus suggestive of a huge esophageal neoplasm. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 The computed tomography scan demonstrated that the entire esophageal cavity had undergone a remarkable expansion and was filled with a heterogeneous density shadow of soft tissue.

5 Fig 4 Postoperative pathology revealed that the lesion was composed of spindle-shaped cells and the inflammatory infiltration was composed predominantly of lymphocytes with a few neutrophils, plasma cells, and eosinophils.
