Challenges in the diagnosis and treatment of giant fibrovascular polyps of the esophagus: Two case reports

Figure 1 Endoscopic images of a giant fibrovascular polyp in the esophagus. A: Endoscopic view showing the polyp occupying the esophageal lumen with its stalk attached to the mucosa; B: Slightly different angle highlighting the surface morphology and spatial orientation of the polyp within the lumen.

Figure 2 Histology results-papillomatous squamous stratified epithelium. Representative area showing the epithelial papillary projections and preserved glandular structures.

Figure 3 Histology results-showing the pathological features of a fibrovascular polyp. A: Overview of the polyp demonstrating fibrovascular stroma with interspersed vascular channels and loose connective tissue; B: Higher-magnification view highlighting the vascular architecture, stromal composition, and interface with the overlying mucosa.

Figure 4 Endoscopic images of a post-endoscopic submucosal dissection defect in the esophagus. A: Endoscopic view immediately after endoscopic submucosal dissection (ESD) showing the mucosal defect and surrounding healthy mucosa; B: Closer view of the post-ESD defect showing the treated mucosal area.

Figure 5 Endoscopic images of a giant fibrovascular polyp from esophagus into the gastric lumen. A. Endoscopic view showing the giant fibrovascular polyp extending from the esophagus toward the gastric lumen; B: Close-up view of the polyp’s base and stalk entering the gastric lumen; C: Oblique view of the polyp showing the stalk’s attachment to the esophageal mucosa and spatial orientation within the lumen.
