These are 6.4cm. 1.2cm. 1.4cm and 4.1cm apart from superior, inferior, medial and lateral resection margins, respectively. Multisected and representative sections are embedded. No.2 specimen labeled as right breast inferior-lateral margin consists of a lump of breast, measuring 3.1x1.2x0.5cm. The specimen is previously marked by purple ink in the resection margin.
