The objective of this study was to evaluate EC expression in sclerosing adenosis, ductal carcinoma in situ and invasive ductal carcinoma. Samples of breast lesions from 44 women were used in this study, comprising cases of sclerosing adenosis (<jats:italic>n<\/jats:italic> = 11), ductal carcinoma in situ (DCIS) (<jats:italic>n<\/jats:italic> = 10) and invasive ductal carcinoma (<jats:italic>n<\/jats:italic> = 23). Immunohistochemical evaluation of EC expression was assessed semiquantitatively and considered negative (&lt;10% of cells with stained cytoplasmic membranes), positive+ (10\u201350% of cells stained) or positive++ (&gt; 50% of cells stained). Fisher's exact test was used to compare the distribution of staining intensity in the lesions (<jats:italic>P<\/jats:italic>&lt; 0.05). There was a progressive loss of EC expression from benign to malignant lesions. This difference was statistically significant when sclerosing adenosis was compared with DCIS (<jats:italic>P<\/jats:italic> &lt; 0.0002), when sclerosing adenosis was compared with invasive ductal carcinoma (<jats:italic>P<\/jats:italic> &lt; 0.008) and when DCIS was compared with invasive ductal carcinoma (<jats:italic>P<\/jats:italic> &lt; 0.007). The present findings point to a significant association between reduced EC expression and the progression and aggressivity of breast lesions. Diagn.
