Atypical ductal hyperplasia
As atypical ductal hyperplasia is a hyperplasia within the functional units of the mammary gland , unit terminal ductal lobules (→ the structure of the mammary gland ), which the constituents of the milk secreting described. Atypical ductal hyperplasia is up to a size of 2 mm.
A typical, conspicuous proliferation of these cells takes place quite physiologically during the conversion to the lactating , i.e. milk-producing, breast, in which the glands branch out and multiply. In atypical ductal hyperplasia, however, the hyperplasia is too large and occurs in unusual, wrong places.
In pathology, atypical ductal hyperplasias are important because histologically they are located between epithelial hyperplasia and highly differentiated carcinoma.
