Splenic metastasis of malignant tumors is relatively rare, and metastasis of colon carcinoma is extremely rarely. We report a case of transverse colon carcinoma with concurrent solitary metastasis to the spleen. A 58-year-old woman found to have fecal occult blood was further found in colonoscopy to have a type2 lesion at the left transverse colon leading to a diagnosis of adenocarcinoma based on a biopsy. Abdominal CT showed a low-density 35×32 mm tumor in the spleen. Ultrasonography showed a similar solitary high-echoic area, the subsequent solitary metastasis of the spleen was treated by simultaneous colectomy and splenectomy. Histopathological diagnosis confirmed intrasplenic metastasis from transverse colon carcinoma. The postoperative progress was favorable and she has no sign of recurrence at present, 14 months after surgery. There are reports of good prognosis following resection of solitary splenic metastasis, so we recommended radical surgery for patients who have colorectal carcinoma with solitary splenic metastasis.
