A small 10-mm nodule was detected on the ventral right side of the anastomosis (arrow) (A). The recurring neoplasm that emerged on the anastomosis was close to the sacrum (arrow head) (B). The positron emission tomography scan revealed abnormal 2-[18F]-fluoro-2-deoxy-d-glucose accumulation in the vicinity of the anastomosis (arrow head) (C). A recurrent lesion with an approximately half-circumference and ulceration was detected on the dorsal side of the anastomosis. Malignant neoplastic cells were also identified in the pathological examination of the biopsy specimen obtained from the anastomotic recurrent tumor (D)Back to article page
