title: Morphometry of the breast fibroadenoma.
abstract: This work is concerned with a morphometric analysis of 23 breast fibroadenomas subdivided into four histological subgroups from purely pericanalicular to purely endocanalicular forms. The volume fractions (Vv) of the lumina and the total volume: epithelial surface ratios (Sv) showed a significant (P less than 0.001) correlation (r = + 0.64). In addition, the Vv and Sv series did not correlate with any of the histological subgroups. The data reported in this work suggest that the ductal epithelium proliferates in fibroadenomas, and that the subtypes are not related to the epithelial growth.
