Abstract

Synchronous esophageal and gastric cancers with the pathologic features of a squamous cell carcinoma are extremely rare. A 57-year-old male visited our hospital with a history of hematemesis and was diagnosed with a synchronous cancer. He underwent a staging work-up, and the resectable lesion in the stomach was operated on following radiologic and endoscopic evaluations. The pathologic examination revealed a synchronous cancer consisting of squamous cell carcinoma in the distal esophagus and the cardia of the stomach. We report a case of a synchronous cancer that was successfully treated by surgical resection followed by concurrent chemoradiotherapy. We also discuss the hypothesis regarding the origin and presentation of the synchronous cancer and highlight the importance of careful surveillance by physicians at the time of diagnosis.

A gross specimen from the stomach after total gastrectomy, pT4N2M0. There is an ulcerofungating mass measuring 6×6 cm in the lesser curvature of the cardia. It is located 1.3 cm from the proximal resection margin and 12.5 cm from the distal resection margin. Both the proximal and distal resection margins are shown to be free of carcinoma (a safety margin of 1.3 cm and a safety margin of 12.5 cm, respectively).
