Lymph node (LN) metastasis of ductal carcinoma in situ with microinvasion (DCISM) is variable (0-14%). To ascertain the role of lymphangiogenesis in LN metastasis in DCISM, we compared the lymphatic vessel density with the presence of LN metastasis in a group of patients that underwent axillary dissection with breast surgery due to DCISM.
