Figure 1 Diagnostic and therapeutic algorithm of gastrointestinal stromal tumor using endoscopic ultrasound-guided fine needle aspiration. Quoted and modified from reference [8,14]. GIST: gastrointestinal stromal tumor; GI: gastrointestinal; SMT: submucosal tumor; EUS: endoscopic ultrasound; EUS-FNA: endoscopic ultrasound-guided fine needle aspiration.

Figure 3 Management process of gastric submucosal tumor (in a case of gastrointestinal stromal tumor) according to our institutional algorithm (Figure 1). Quoted and modified from reference [15]. A: Esophagogastroduodenoscopy (EGD) shows submucosal tumor in the lower body of the stomach; B: Endoscopic ultrasound (EUS) reveals 2.5 cm subepithelial hypoechoic solid tumor with continuity to proper muscle layer (arrow-mp); C: Puncture of the small gastrointestinal stromal tumor (GIST) under EUS guidance. Arrow: tip of needle; D: The immunohistochemical fnding of endoscopic ultrasound-guided fne needle aspiration (EUS-FNA) specimen of GIST. The tumor is diffusely positive for c-kit.

Figure 6 Management process of gastric submucosal tumor (in a case of ectopic pancreas) according to our institutional algorithm (Figure 2). Quoted and modified from reference [15]. A: Esophagogastroduodenoscopy (EGD) showing submucosal tumor in the middle body of the stomach; B: Endoscopic ultrasound (EUS) revealing 1.5 cm subepithelial hypoechoic solid tumor with continuity to proper muscle layer (arrow-mp); C: Puncture of the small submucosal nodule under EUS guidance. Arrow: tip of needle; D: Histology of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) specimen reveals pancreatic acinar cells.

Figure 7 Management process of gastric submucosal tumor (in a case of B-cell lymphoma) according to our institutional algorithm (Figure 2). Quoted and modified from reference [15]. A: Esophagogastroduodenoscopy (EGD) showing submucosal tumor in the middle body of the stomach; B; Endoscopic ultrasound (EUS) reveals 1.5 cm subepithelial hypoechoic solid tumor within submucosal layer. Proper muscle layer (arrow-mp) is intact; C: Puncture of the small gastric malignant lymphoma under EUS guidance. Arrow: tip of needle; D: The immunohistochemical findings of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) specimen reveals CD-20 positive diffuse large B cell lymphoma.
