Colorectal metastasis is rare and can be confused with primary colorectal cancer. We report the case of a 63-year-old patient who presented with synchronous metastasis of the rectosigmoid junction and ovarian cancer. Initially thought to be a Krukenberg tumor, the diagnosis of metastasis from ovarian origin was confirmed through an immunohistochemical study of the colonic biopsy.
Keywords: biomarker cancer antigen 125 (ca125); immunohistochemical; metastatic ovarian cancer; pegylated liposomal doxorubicin; platinum-sensitive disease; synchronous tumors.
