Endoscopic treatment of calcifying fibrous tumor of the esophagus combined with esophageal cancer: A case report

Figure 1 Preoperative multimodal evaluation of the esophageal lesions. A: White-light endoscopy showing a submucosal tumor-like elevation in the upper esophagus; B: White-light endoscopy showing a superficially elevated mucosal lesion with grayish-white exudate on the surface; C: Contrast-enhanced chest computed tomography of the chest (sagittal view) shows calcification within the lesion; D: Magnifying narrow-band imaging endoscopy reveals type B2 intrapapillary capillary loops; E: Preoperative biopsy histopathology showing high-grade intraepithelial neoplasia of the esophageal squamous epithelium; F: Lugol iodine staining showing an unstained area of the lesion; G: Endoscopic ultrasonography shows the lesion as a hypoechoic mass with local hyperechoic areas.
