Successful endoscopic removal of a giant upper esophageal inflammatory fibrous polyp

Figure 1 Imaging of esophageal polyp. A: Barium swallow showed a giant esophageal polyp (arrow), which was free from the middle and lower esophageal wall; B: Gastroscopy showed the polyp with smooth overlying mucosa (at 18 cm from the incisors); C: EUS revealed well-distributed, low-echo-level lesions at root of the polyp (white arrows), excluding echoless lumen-like structures.

Figure 2 Esophageal polyp removal. A: Residual polyp (white arrow) after polypectomy at the left wall of the esophagus (18 cm from incisor). A nasogastric tube (black arrow) used for suction (size 16 Fr) was placed over the right wall of the esophagus; B: Hemoclips (white arrow) were applied to the residual polyp; C: After application of the hemoclips (black arrow) to the residual polyp (white arrow).

Figure 3 Polypectomy specimen and its pathology. A: The resected esophageal lesion measured 17 cm in length, and the neck, body and tail of the lesion measured 1, 3 and 5 cm, respectively; B: HE staining (original magnification, × 200) showed the presence of lots of fibroblasts, with some acidophilic cells, plasma cells and adipose cells; C: Immunostaining (original magnification, × 200) for vimentin showed strong staining of the cells.
