Histopathology of Fibroadenoma of the Breast
Frequencies of both usual ductal and atypical hyperplasia (7.9% and 1.2%) were somewhat lower in our study than those found by Dupont et al 2 (13.7 % and 1.7%).

Usual ductal hyperplasia displays a luminal staining pattern with expression of both CK5/14 and CK7/18. Residual p63 was observed in the nuclei of the myoepithelium (photos 2/3).

Core Needle Biopsy of Challenging Benign Breast Conditions:
Discussion ADH The fundamental definition of ductal epithelial hyperplasia is an increase in the number of cells superior to the basement membrane beyond the usual two. "Usual" or "ordinary" ductal hyperplasia is the most common variety; it is characterized by proliferation of a heterogeneous ...

Histopathology of Fibroadenoma of the Breast
Only the most advanced lesion of the so-called usual ductal hyperplasias (mild, moderate or florid) was scored, i.e. if moderate and florid ductal hyperplasia were both present, only florid ductal hyperplasia was scored.
