Solitary splenic metastasis from gastric cancer: report of a case.

We report a rare case of metachronous and solitary metastasis to the spleen from gastric cancer. A 69-year-old man who had undergone a distal gastrectomy for gastric cancer 48 months earlier was found to have a solitary lesion in the spleen, and an increased serum carcinoembryonic antigen (CEA) level. The patient underwent a laparotomy for suspected metastasis to the spleen. At laparotomy, a tumor was found in the upper pole of the spleen without involvement of other organs, and a splenectomy was performed. Histological examination confirmed that the splenic tumor was a well-differentiated adenocarcinoma similar to the primary gastric cancer. The postoperative course was uneventful and his serum CEA decreased to within normal levels. The patient died of multiple metastases to the liver and peritoneal dissemination 40 months after the splenectomy.
