ISOLATED SPLENIC METASTASIS FROM CARCINOMA OF THE COLON

Abstract

Splenic metastasis is uncommon and usually occurs in a setting of widespred visceal metastases. A case of isolated intrasplenic metastasis from sigmoid colon cancer is reported.
A 77-year-old woman was admitted to the hospital because of pneumonia. During treatment, she complained of nausea and appetite loss. Barium-enema examination showed an apple core sign in the sigmoid colon and colonfiberscopy revealed irregulary mucosa, and adenocarcinoma was evidenced by punch biopsy. Computed tomography disclosed hypodense lesions in the spleen. Abdominal ultrasonography showed a hyper echoic area in the spleen. From these findings we diagnosed isolated intrasplenic metastasis from sigmoid colon cancer. Sigmoidectomy and splenectomy was performed. The histological diagnosis confirmed intrasplenic metastasis from sigmoid colon cancer.
In the literature, there are reports of good prognoses, following resection of the solitary splenic metastasis. Therefore, we recommend this procedure in case of solitary splenic metastasis.
