Here, we performed a laparoscopic resection for a benign Schloffer tumor that showed positive F\u201018 fluorodeoxyglucose (FDG) positron emission tomography (PET) at the port site of a laparoscopic right hemicolectomy for advanced colon cancer. We report a case in which systemic chemotherapy was avoided as a result of the histological examination following the laparoscopic approach. A 66\u2010year\u2010old female, who underwent laparoscopic right hemi colectomy for stage IIIA ascending colon cancer, was revealed an enhanced mass at the right side of the abdominal subcutaneous layer. PET examination showed a high accumulation of FDG. Laparoscopic tumor resection was performed. Pathological findings reported the formation identical to the Schloffer tumor. Schloffer tumor, which is rare, should be considered as one of the differential diagnoses for tumor with FDG\u2010PET positivity at the port site during the postoperative surveillance period of colorectal cancer.<\/jats:p>","DOI":"10.1111\/ases.13267","type":"journal-article","created":{"date-parts":[[2023,12,2]],"date-time":"2023-12-02T16:18:19Z","timestamp":1701533899000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Laparoscopic
