Abstract

Introduction: Colorectal adenocarcinoma metastasis to the vagina can occur months after the primary tumor resection. Most of the time, bleeding is the main alarming symptom. The optimal treatment involves surgical excision followed by reconstruction to prevent the lymphatic networks in the rectovaginal septum from serving as a potential route of spread. Several successful vaginal reconstruction options have been reported. 
Case Presentation: We describe a 32-year-old woman who had previously undergone an abdominoperineal resection for rectal cancer and was now suffering from rectal adenocarcinoma vaginal metastasis. An inferior gluteus perforator flap (IGAP) repair was carried out following posterior vaginectomy after a comprehensive multidisciplinary examination. This flap can address perineal dead space and reconstruct the neovaginal area, eliminating the need for a second flap and significantly reducing donor morbidity. The lesson from this case is that vaginal metastases can still develop even after removing the primary colorectal tumor. 
Conclusion: One-step surgical excision and perineal repair can result in an enhanced quality of life and a good prognosis.
