Figure 1 Barium esophagogram showed that the lower esophagus was compressed to approximately 5. 5 cm (arrowheads).

Figure 2 Endoscopy and endoscopic ultrasound image. A: Esophagogastroduodenoscopy showed a large lesion in the esophagus 32-38 cm from the incisors (arrowheads); B: Endoscopic ultrasound showed a hypoechoic lesion, likely originating in the muscularis propria.

Figure 3 Chest computed tomography revealed a mass approximately 53 mm × 39 mm × 50 mm protruding from the lower esophagus (arrowheads).

Figure 4 Histopathological examination revealed spindle-shaped cells arranged in interlacing fascicles (hematoxylin and eosin stain, × 200).

Figure 5 Immunohistochemical examination revealed SOX10 protein positivity (× 200).
