(A) Contrast-enhanced computed tomography scans obtained 2 days after admission showed a circumferential mass in the middle thoracic esophagus spanning. (B) Endoscopic examination findings show a large mass located 29 cm from the upper incisors that was almost completely obstructive. (C) Pathologic findings from the endoscopy: poorly differentiated squamous cell carcinoma (hematoxylin and eosin staining, ×100).

(A) Intraoperative examination showed that the tumor did not invade adjacent organs. (B) The tumor was bisected, revealing a mass about 9.0 × 2.5 × 2.5 cm in the esophageal lumen with only a thin pedicel connecting it to the mucous membrane of the esophagus. (C) Pathologic findings from the postoperative specimens, revealing two tumor components: squamous cell carcinoma and malignant spindle-shaped cells (hematoxylin and eosin staining, ×100).
