Submucosal Tumor of the Stomach With Drastic, Short-term Changes in Morphology

Question: A 47-year-old man was referred to our institution for detailed examination of gastric tumor. One year previously, the patient was diagnosed as  having a submucosal tumor in the upper gastric corpus by screening esophagogastroduodenoscopy (Figure A). On admission, laboratory tests were within normal limits and Helicobacter pylori was negative as determined by the stool antigen test and the serological test. Esophagogastroduodenoscopy revealed that the lesion had increased in size with ulceration (Figure B).
