Multiple primary tumors are rare but their incidence is increasing. We aimed to present a case report about a patient with synchronous gastric and colon cancer, who has undergone a simultaneous resection of both tumors and developed (preventable) postoperative complications. A 69-year-old male patient, who was diagnosed with severe acute respiratory syndrome coronavirus-2019 infection 3 months ahead of his admission, presented to the Trakya University due to gastric bleeding. Colonoscopy and esophago gastro duodenoscopy were performed upon complaints. The patient was diagnosed with synchronous gastric and colon adenocarcinoma. Total gastrectomy, left hemicolectomy, and Roux-en-Y esophagojejunostomy were performed simultaneously. Although there were no postoperative surgical complications, the patient developed a pulmonary embolism. In the presence of a gastrointestinal tumor, the synchronous or metachronous tumor should also be evaluated. The most appropriate surgical treatment is simultaneous resection of both tumors. Physicians should also consider the risk of a pulmonary embolism that may develop after these major surgeries.
