Large-format section of lumpectomy specimen from Figure 9. Analysis of neoplasm size, extent, and margin status. Invasive grade 2 ductal carcinoma is outlined with solid black line, 15 mm greatest dimension. Grade 3 DCIS extent outlined with solid red line, 60 mm overall. Circumferential margins marked with broken line. Specimen was sectioned in the sagittal plane to best evaluate critical anterior-superior margin. DCIS extends to within 2 mm of intersection of anterior and superior margins (arrow). Scale: small divisions = 1.0 mm (H&E).
