[A case of metachronous ovarian metastasis after curative surgery of colon cancer with simultaneous hepatic metastasis].

The patient was a 51-year-old woman who presented with nausea, vomiting, and abdominal pain. Detailed examination revealed a carcinoma of the descending colon with simultaneous hepatic metastasis. Because the carcinoma comprised a circumferential stenotic lesion and resection of the hepatic metastasis was feasible, combined left hemicolectomy and hepatectomy were initially performed. During postoperative adjuvant chemotherapy, the hepatic metastasis was observed to increase in size, and therefore, a second hepatectomy was performed approximately 2 years and 6 months after the initial surgery. Adjuvant chemotherapy was subsequently continued for approximately 1 year. A metastatic ovarian tumor was identified on abdominal computed tomography (CT) approximately 1 year after chemotherapy was discontinued. Bilateral salpingo-oophorectomy was performed approximately 3 years and 6 months after the initial surgery. Histopathological examination revealed the lesion to be a colon carcinoma metastasis.
