Summary:INTRODUCTIONExtra-anastomotic intraluminal recurrence of the colon cancer after curative surgery was rarely reported but intraluminal ileal relapse has not been described to date.We report a case of intraluminal ileal tumor arising after curative right hemicolectomy that could be ascribed to an implantation of exfoliated cancer cells. CASE REPORTA 71-years old man was admitted with no metastatic stenotic adenocarcinoma of the hepatic flexure and submitted, without preoperative bowel preparation, to right hemicolectomy using a "no-touch" technique. Histology showed moderately differentiated adenocarcinoma without lymph nodes involvement (pT3N0). No adjuvant therapy was prescribed. First colonoscopy three months after surgery was negative but a second endoscopic examination nine months later revealed an ileal neoplasia, presenting like an ulcer 10 cm proximally to ileocolic anastomosis. A new ileo-colic resection including past anastomosis was performed with curative intent. Pathological examination showed moderately differentiated adenocarcinoma extended to peri-visceral fat tissue with 10 tumor-free lymph nodes. (pT3N0). Six courses of Capecitabine adjuvant chemotherapy was prescribed and 32 months after second surgery, the patient is alive without disease. DISCUSSIONIn the present case, the relatively short time from the primary surgery and the fact that recurrence occurred outside the anastomosis suggest that implantation of exfoliated malignant cells seems to be the main pathogenetic mechanism. We suppose that the high grade of primary cancer and the occlusive condition could have promoted the cancer cells reflux through the ileocecal orifice and in the transverse colon. CONCLUSIONThis case seems to confirm the intraluminal implanting capacity of exfoliated carcinoma cells.
