case_images: The result showed a large submucosal tumor (SMT) in the gastric body ( Figure 1A ) and Helicobacter pylori (H. pylori) infection. ESE procedure was performed at the request of the patient and her family. En-bloc resection was achieved without any significant adverse events ( Figures 1B, C ). With the patient's family's full informed consent, the specimen was temporarily placed in the stomach and was completely removed using a retrieval net two days later ( Figure 1D ).
case_images: (A) Contrast-enhanced computed tomography scan revealed a 37mmx37mmx30mm-sized, well-defined, mild-to-moderate enhanced, and homogeneous round mass. (B) Endoscopic ultrasonography showed a hard, heterogeneous hypoechoic tumor, appearing to originate from muscularis propria. (C, D) Histology showed the presence of abundant hyalinized collagen, along with focal dystrophic calcifications and a lymphoplasmacytic infiltrate (Hematoxylin-eosin stain).

case_images: Contrast-enhanced computed tomography (CT) scan of the chest, entire abdomen, and pelvis revealed a 37mmx37mmx30mm-sized, well-defined, mild-to-moderate enhanced, and homogeneous round mass in the stomach ( Figure 2A ). Endoscopic ultrasonography (EUS) showed the heterogeneous hypoechoic tumor with an elasticity score of 7.64, which appeared to originate from muscularis propria ( Figure 2B ). Histology diagnosed gastric CFT with the presence of abundant hyalinized collagen, along with focal dystrophic calcifications and a lymphoplasmacytic infiltrate ( Figures 2C, D ).
