Breast adenopathy
Adenosis of breast is hyperplasia of mammary epithelium and fibrous tissue, which is sometimes accompanied by cyst formation and epithelial metaplasia to other morphological features. Is the early stage of mammary dysplasia. The main changes are the obvious focal hyperplasia of the acinus and small ducts of the breast, and different degrees of connective tissue hyperplasia. The leaflet structure basically loses its normal shape, and even acinar epithelial cells are scattered in the fibrous matrix. According to the development of the lesion, it can be divided into 3 stages: lobular hyperplasia, fibroadenosclerosis and sclerosing adenopathy. There are reports in the literature that in addition to lobular hyperplasia, no canceration was found, and canceration was present in the latter two stages. This phenomenon has important clinical significance.
