We report the case of a patient with single lung metastasis after gastric cancer surgery. A 66-year-old man was diagnosed with gastric cancer and underwent total gastrectomy. We diagnosed him with poorly differentiated adenocarcinoma T3 (SS) N0M0 p-StageIIA according to the Japanese Classification of Gastric Carcinoma 14th edition. Surveillance chest CT revealed a nodule in the middle lobe of the right lung. The nodule showed an increasing size. Suspecting a metastatic lung tumor, we performed thoracoscopic right middle lobectomy. Pathological examination revealed that the tumor was consistent with metastasis from gastric cancer. He is currently alive and has not experienced recurrence during the 39 months since the lung resection.
