BackgroundGastric metastases (GMs) are rare and often accompanied with synchronous metastases of other organs. Synchronous isolated GMs from ascending colon carcinoma are uncommon and rarely studied. GMs may be confused with primary gastric tumors.MethodsA 45-year-old man presented to our hospital with abdominal distensionand anal pendant expansion. The abdominal physical examination was negative. The positive fecal occult blood test and the negative tumor marker were obtained. Colonoscopy and gastroduodenoscopy revealed a polypoidal lesion in the ascending colon and a polypoid mass in the gastric body, respectively. CT showed the thickened wall of ascending colon and polypoid mass in the gastric body with homogenous enhancement. Additionally, synchronous gastric metastases from the ascending colon carcinoma were confirmed by pathology after laparoscopic right hemicolectomy and partial gastrectomy. After 13 individual doses of fluorouracil (2.8 g/time), calcium leucovorin (0.8 g/time), and oxaliplatin (85 mg/time), the patient was discharged without any discomfort, without any additional metastases detected during the following 18 months.1.ResultsA rare case of synchronous isolated gastric metastasis from ascending colon carcinoma was confirmed by computed tomography (CT) and pathological diagnosis.ConclusionGM may appear as a polypoid lesion. Surgery combined with chemotherapy may improve the prognosis in patients with synchronous isolated GM.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
