A Case of Metastasis to the Vagina from Rectal Cancer

Abstract

A rare case of metastasis to the vagina from rectal cancer is described. An 81-year-old woman was admitted to our hospital because of melena. She underwent a super-low anterior resection (inter sphincter resection) for rectal cancer. Pathological diagnosis revealed well-differentiated adenocarcinoma with T3, N0, M0 (final stage II). A small SMT was found at the anastomotic site by digital examination 2 years after the initial operation. It was removed trans-anally, and local recurrence from rectal cancer was confirmed pathologically. Upon further examination for vaginal bleeding, a tumor 3cm in diameter was confirmed in the left posterior wall of the vagina 26 months after the initial surgery. The tumor was removed trans-vaginally. The pathological diagnosis was metastasis of rectal cancer and cancer cells were found in the vessels around the tumor.
