Adenosquamous carcinoma of the stomach is a very rare disease, consisting of less than 0.4 % of all stomach cancer. From 1991 to 2013, a total of 2800 patients received gastrectomy for gastric cancer at Taipei Veterans General hospital. Among them, seven patients (0.25 %) diagnosed as adenosquamous carcinoma were enrolled. The clinicopathologic characteristics and prognosis were analyzed. The mean age of the seven patients was 62.3 years-old. There were 5 males and 2 females. Six patients were stage III disease and one patient was stage IV disease. Four patients finally died of gastric cancer. Only one patient had no recurrence until death. Among the seven patients, adenocarcinoma component comprises the majority of the metastatic lymph node in 6 patients (85.7 %). The only one patient with major squamous cell carcinoma component in metastatic lymph node had no tumor recurrence till death. Adenosquamous carcinoma of stomach is a rare disease and is associated with a poor prognosis. The component of adenocarcinoma and squamous cell carcinoma in the metastatic lymph node may influence the prognosis.
