Introduction: An isolated vaginal metastasis from a primary colorectal adenocarcinoma is extremely rare. Based on meticulous literature review, only seven cases were reported from 1956 – 2013. Case Presentation: We present a case of a 52-year-old female patient diagnosed with rectal adenocarcinoma, underwent low anterior resection of the primary tumor, and then was found to have an asymptomatic isolated vaginal metastasis that was completely excised. Conclusion: Isolated vaginal metastatic disease is one of the rarest entities in surgical oncology with only limited cases being reported in the literature. A diagnosis can be challenging if the metastatic lesion is small and asymptomatic even with the most advanced radiological assessment tools. A meticulous examination should be done pre-operatively in order to rule out such diagnosis.
