INTRODUCTION: Extensive intraductal carcinoma is proposed for tumors in which the intraductal component comprises 25% or more of the area encompassed by the infiltrating tumor.(1). Ductal carcinoma in Situ with a micro invasive component accounts for less than 1% of all breast cancers and 13.5% of all DCIS have a microinvasive component.( 2). The increased rate of early detection of breast cancer due to widespread mammographic screening has led to an increased incidence not only of in situ but also microinvasive carcinoma. DCIS with micro invasion (DCISM) results in axillary lymph node metastases, statistically significant independent predictors of lymph node metastases in DCISM are comedo DCIS.
