Abstract
We experienced the case of a solitary splenic metastasis from a sigmoid colon cancer. The patient was a 61-year-old woman who had undergone a laparoscope-assisted sigmoid colon resection for cancer of the sigmoid colon in June 1998. The patient's postoperative course was uneventful, but her serum CEA level increased 54 months after the operation and a splenic metastasis was revealed by CT&MRI studies. A laparoscope-assisted splenectomy was performed, based on a diagnosis of a solitary splenic metastasis, in January 2003. Pathological examination showed the resected tumor to be a moderately differentiated adenocarcinoma. The patient's postoperative course was uneventful, and her serum CEA level normalized. No signs of recurrence have been observed 15 months after the splenectomy. This case is the 28th report of a metachronous solitary splenic metastasis arising from colon cancer to be reported in Japan.
