[A Resected Case of the Vaginal Metastasis from Rectal Cancer]

The vaginal metastasis from colorectal cancer has rarely been reported. Here, we report a resected case of the vaginal metastasis from rectal cancer. A 51-year-old woman underwent radical hysterectomy and bilateral oophorectomy for uterus cancer. Five years after the operation, vaginal tumor was observed during an internal examination. Biopsy was positive for adenocarcinoma. Enhanced computed tomography demonstrated the wall thickening of the lower rectum and the mass of 20 mm at the inferior lobe of the left lung. Colonoscopy revealed the wall thickening of the lower rectum, and biopsy indicated a diagnosis of rectal cancer. We performed abdominoperineal resection and partial resection of the vagina. Pathological examination confirmed the vaginal metastasis from the rectal cancer.
