Abstract
Splenic metastasis is uncommon and usually occurs in patients with widespread visceral metastases. We report a case with cancer of the sigmoid colon who had a synchronous solitary splenic metastasis. An 85-year-old woman developed constipation. On barium-enema, an apple core sign was seen in the sigmoid colon. On abdominal CT scan, a low density area in the spleen was noted ; her serum CEA was elevated. An isolated intrasplenic metastasis from sigmoid colon cancer was suspected. The patient had a sigmoidectomy and splenectomy. Based on the histopathology, a diagnosis of sigmoid colon cancer and a splenic metastasis of the colonic cancer was made. The woman's postoperative course was uneventful, and her serum CEA normalized. However, 4 months postop, her serum CEA increased. Multiple metastasis in the kidneys and lungs were found 8 months postop. The patient died 25 months postop.
