Histological analysis of the second lesion revealed a coexisting tubular adenoma with low-grade intestinal dysplasia and a NET G1 (Ki67 2%, well-differentiated tumor cell nets surrounded by fibrous stroma, chromogranin and synaptophysin positive staining, no mitosis), both extending to the deep resection margin (R1) and measuring 14 mm in size. Here, MKI67 is linked to neoplasm.
