Herein we report on a case of gastric GIST that recurred locally 11 years after surgery, which was successfully resected. The case concerned a male patient in his 70s. In March 2011, the patient underwent proximal gastrectomy for a submucosal tumor in the gastric cardia. The patient was diagnosed with high-risk GIST based on the pathological findings and was treated with imatinib as postoperative adjuvant therapy for 3 years. The patient then continued follow-up as an outpatient. A follow-up CT scan performed in March 2022 showed a mass shadow on the ventral side of the esophagogastric anastomosis, and a biopsy revealed a diagnosis of GIST. The tumor was resected locally as a recurrent gastric GIST.
