Abstract
A 71-year-old woman underwent laparoscopically assisted ileocecal resection at another hospital in 2013 (T3N1H0P0M0 Stage IIIa colon cancer). She underwent postoperative follow-up at the same hospital after adjuvant chemotherapy. She experienced atypical genital bleeding 7 months after the surgery, and visited a gynecology clinic. The findings of the examinations indicated cancer of the uterine body that had invaded to the cervix ; therefore, she was referred to our hospital. Computed tomography and magnetic resonance imaging showed that a tumor lesion was located at the posterior of the uterine cervix, and the boundary between the tumor lesion and rectum was partially unclear. A biopsy of the uterine cervix showed adenocarcinoma that was cytokeratin 7 negative and cytokeratin 20 positive by immunohistochemistry, indicating a uterine cervix metastasis from cecal cancer. A total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed by a gynecologist. The patient's postoperative course was uneventful, and she was discharged from our hospital 12 days after surgery. Histopathological examination showed a well to moderately differentiated tubular adenocarcinoma, and she was diagnosed with uterine cervix metastasis from cecal cancer. She remained disease-free after surgery. Uterine cervix metastasis from colon cancer is very rare. We reported this case and reviewed previous studies and case reports.
