Summary

Description
English: Histological appearance of atypical ductal hyperplasia (ADH) and immunohistochemical phenotype.
- A - One focus (< 2 mm) of two architecturally disarranged cross sections of tubuli showing a monotonous intraductal proliferation with secondary intraluminal architecture. Hematoxylin and Eosin stain.
- B - One area of an ADH with associated calcifications intraluminal. Hematoxylin and Eosin stain.
- C - Higher magnification of ADH shows low-grade nuclear atypia and monotonous cell proliferation along with secondary intraluminal architecture. Hematoxylin and Eosin stain.
- D - Strong and uniform expression of estrogen receptors (ER). ER immunohistochemistry.
- E - Lack of basal cytokeratins (CK5/6). CK5/6 immunohistochemistry
