Objective As is well-known gastric adenocarcinoma is one of the most common tumors.But gastric squamous cell carcinoma is rather rare,with a global incidence of 0.04% to 0.07% of gastric cancer.So far,less than 100 cases have been reported in the English literature,and early cases of gastric squamous cell carcinoma are rarer.Therefore,knowledge about pathogenesis,treatment and prognosis of the disease is limited.
