Abstract
We report a rare case of gastric cancer metastatizing from ovarian cancer. A 46-year-old woman with advanced gastric cancer and epigastral discomfort and weight loss underwent subtotal gastrectomy, but a tumor appeared over the lower abdomen during adjuvant chemotherapy. A complete gynecological examination delivered a definitive diagnosis of ovarian cancer. She underwent total abdominal hysterectomy and bilateral salpingooophorectomy. The comparison of ovarian and stomach tissue in postoperative micropathological findings indicated a stomach lesion in submucosa and immunohistological findings for CA125 suggested gastric cancer metastatizing from ovarian cancer.
