Plexiform angiomyxoid myofibroblastic tumor of stomach: A rare case

Figure 1 Images from outpatient upper gastrointestinal endoscopy. Submucosal tumor with intact overlying mucosa is located in the anterior wall of the antrum. It partially obstructs the gastric outlet.

Figure 2 Endoscopic images from our case of plexiform angiomyxoid myofibroblastic tumor show multinodular tumor-like mass protruding into the gastric lumen after performed buttonhole biopsy. This mass blocks the pylorus resulting in the stasis of gastric content.
