Twenty\u2010four years later, the patient developed an implantation cyst at the anastomotic site. Two years after the diagnosis, colonoscopy revealed a disintegrated area in the lesion, and pathological examination of the biopsy specimen revealed adenocarcinoma. Due to the suspicion of invasion into the surrounding organs, the patient underwent laparoscopic total pelvic exenteration after neoadjuvant chemoradiotherapy. A transabdominal and transperineal endoscopic approach was used for safe <jats:italic>en bloc<\/jats:italic> excision of the tumor. Pathological examination of the specimen confirmed mucinous adenocarcinoma arising from the implantation cyst. Although an implantation cyst is considered benign, it is important to suspect malignant transformation when its appearance changes. For the accurate diagnosis of implantation cysts, surgeons, endoscopists, and radiologists should be aware of this disease.<\/jats:p>","DOI":"10.1111\/ases.13178","type":"journal-article","created":{"date-parts":[[2023,3,8]],"date-time":"2023-03-08T05:25:27Z","timestamp":1678253127000},"page":"558-562","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Total
