A 70-year-old man underwent total gastrectomy with lymph node dissection (D1+α) under a diagnosis of multiple gastric cancers in September 2000. Abdominal computed tomography showed a solitary splenic tumor about 10 cm in diameter in October 2002, necessitating TS-1 therapy. Closer examination showed no metastatic lesion in other organs, so we conducted surgery under a diagnosis of solitary metastasis to the spleen from gastric cancer in February 2003; i. e. splenectomy with resection of the diaphragm. Histopathological examination showed moderately differentiated adenocarcinoma of the spleen, histologically compatible with metastasis from gastric cancer. He remains recurrence-free a year later. Cancer rarely metastasizes to the spleen except in terminal status. Radical surgery is thus recommended for gastric carcinoma patients who have metachronous splenic metastasis.
