The relapses of rectal cancer are most frequently localized in the pelvis, liver, and pelvic and para-aortic lymph nodes and lungs, whereas the vagina is an unusual site. We present here a 60-year-old woman presenting with lower abdominal discomfort 23 months after radical resection of rectal adenocarcinoma. An isolated, solitary, hypermetabolic mass in the right part of the vagina was detected by 18F-FDG PET/CT. Ultimately, the vaginal neoplasm was proved to be adenocarcinoma of rectal origin based on its shared histologic features and compatible immunostaining profile.
