Abstract
A 17-year-old man was seen at the medical clinic because of suffering from hematochezia for 7 years. Colonoscopy showed a white granular tumor occuping almost all round of the anal verge. Biopsy revealed serrated adenoma (SA). Abdominal CT and PET revealed no metastatic lesions. CEA and CA19-9 were negative. The SA was localized on lower rectum, so transanal submucosal dissection was performed. Pathologocal diagnosis was SA with moderate grade dysplasia in the mucosal layer. The tumor margin was enough. The patient was discharge 8 days after the surgery. Transanal resection of juvenile SA on the lower rectum, which was very rare, was performed, considering the function of the anus.
