intraductal proliferations of the breast

The proliferation of intraductal mammary epithelium forms a continuum that begins with intraductal hyperplasia and ends with ductal carcinoma in situ / DCIS.

Atypical intraductal hyperplasia is the midpoint between the benign and malignant poles of this proliferative continuum.

By defining the histological criteria for atypical intraductal hyperplasia , distinction from ordinary intraductal hyperplasia and the non-comedo forms of ductal carcinoma in situ becomes easier.

Histopathologic criteria have been defined for atypical intraductal hyperplasia , ductal carcinoma in situ DCIS, and intraductal hyperplasia and their relative risks for the development of invasive breast carcinoma.
