[The case of a solitary pulmonary tumor which could be diagnosed as early gastric cancer recurrence by detailed pathological examinations].
We report the case of a solitary pulmonary tumor, which was diagnosed as recurrent early gastric cancer by detailed pathological examinations. A 59-year old man initially underwent total gastrectomy for gastric adenocarcinoma located at the esophago-gastric junction. A pathological examination indicated a papillary adenocarcinoma (pap ) that had invaded the submucosal layer (sm²), but had not metastasized to the regional lymph nodes (n0). The final diagnosis was P0H0M0T1bN0, Stage IA. Chest computed tomography (CT) 30 months after primary surgery indicated a solitary tumor with a diameter of 9 mm at S3 of the left lung. A positron emission tomography (PET)-CT scan showed an accumulation of ¹⁸F-fluordeoxy-glucose (FDG18) at the same location. Lung cancer was suspected and the patient was given a left upper lobectomy. The resected tumor was diagnosed as gastric cancer metastatic adenocarcinoma by permanent pathological examination. The tumors showed similar histology and immuno histochemical findings for CK7, CK20, TTF-1, SP-A, CDX-2, and HER2 . Early gastric cancer is an almost curable disease and recurrence is very rare. We report the details of this case and review the literature.
