CASE SUMMARY A 54-year-old otherwise healthy woman presented for screening colonoscopy, during which 4 pedunculated 5- to 12-mm polyps distributed throughout the colon were found (Fig. 1). The 12-mm sigmoid polyp was removed with hot snare polypectomy in a nonpiecemeal fashion. Pathology demonstrated 3 tubular adenomas and a poorly differentiated invasive carcinoma in a sigmoid polyp without tumor budding, invading 0.8 mm into the submucosa, with lymphovascular invasion and with a deep margin of 0.6 mm. The next week, she underwent repeat flexible sigmoidoscopy with tattooing of the polypectomy site. She had a normal staging CT chest/abdomen/pelvis as well as CEA level and later underwent uneventful laparoscopic sigmoid resection, which included the area of endoscopic tattoo. Final pathology confirmed the presence of the tattooed area and polypectomy scar and showed no residual primary tumor and 2/18 positive lymph nodes (Fig, 2). She was referred to medical oncology for adjuvant chemotherapy.
