Endoscopic palliative resection of a giant 26-cm esophageal tumor: A case report

Figure 1 Timeline of the patient with esophageal carcinosarcoma.

Figure 2 X-ray barium meal examination showing a huge intraluminal stalk-like mass along the middle and lower esophagus.

Figure 3 Computed tomography showing a prominently enhanced anterior area of the giant mass beside the esophageal wall (orange arrow), and the maximum sectional area was about 5. 6 cm × 3.5 cm.

Figure 4 Endoscopy. A: The giant mass was polypoid, gray-white, almost filling the whole esophageal lumen (white light), but the endoscope could still pass through; B: The giant polypoid mass was brown, as revealed by narrow-band imaging; C: The bulky pedicle of the mass (orange arrow); D: The wound was intact after cutting off the giant mass.

Figure 5 Postoperative pathology. A: Hematoxylin–eosin staining showing esophageal squamous cell carcinoma (a) with sarcomatoid component (b); B: Magnification of the sarcomatoid component; C: PCK staining; D: CD34 staining; E: Desmin staining; F: S-100 staining.

Figure 6 The giant mass was assembled after pulling out and was about 26 cm × 5 cm × 4 cm in size.

Figure 7 Endoscopic reexamination after 1 mo revealed no esophageal obstruction. A: White light; B: Narrow-band imaging.
