ABSTRACT: Histological Subtypes of Ductal Carcinoma in situ of the Breast Background: It has become common to divide ductal carcinoma in situ (DCIS) of the breast into two main groups, comedo or noncomedo by tumor morphology. But noncomedo DCIS can be further stratified into several morphological patterns that exhibit several different growth patterns and most DCIS lesions have more than one pattern. In this study, DCIS elements were classified by morphological pattern and the association between predominant or recessive elements of DCIS lesions and clinicopathological findings was evaluated. Conclusions: DCIS lesions containing a comedo or cribriform element are more likely to have microscopic spread and involvement of lobules and DCIS lesions containing a papillary element are likely to be multicentric, whether the pattern are predominant in the tumor or not.
