Abstract

<p>A 65-year-old man presented to our hospital with a chief complaint of epigastric discomfort. Upper gastrointestinal endoscopy showed a submucosal tumor at the esophagogastric junction. Histopathological examination was positive for c-kit and CD34, and he was diagnosed with a gastric gastrointestinal stromal tumor (GIST). Computed tomography showed several swollen lymph nodes with a diameter of 3-5 mm in #1 and #2. Intraoperatively, lymph node #2 was sampled for a rapid pathological diagnosis, and metastasis was detected. Laparoscopic proximal gastrectomy with D1+ lymph node dissection was performed. Postoperative pathological examination showed a GIST, 30 mm in diameter, and one lymph node metastasis in #2. In general, gastric GISTs are treated with partial resection only, and lymph node dissection is not performed. However, it is necessary to recognize that there are rare cases of lymph node-positive GISTs, and this case is reported along with a review of the literature.</p>
