Breast Pathology performance by illness

Breast lesions by illness for the specimen, a diffuse disease or limitations, hard tough and dense texture, color or grey huangbai, no envelope, the section that a number of particle sizes ranging from translucent; such as cystic Hyperplasia, can see small Cyst, wall mostly smooth, green or yellow capsule containing brown viscous liquid, granular or in some there are papillary of the intracavitary outstanding. Breast Pathology by the illness on the one hand, for the performance of the cystic ductal breast expansion, ranging from the size of a cyst on the other hand for the performance of duct epithelial have different degrees of papillary hyperplasia, lobular within and between the fibrous tissue lobular have varying degrees Proliferation. As the breast by sick form of complex organizations, his organization has a variety of classifications. For scholars of breast structure in accordance with the volume and shape of abnormal breast tissue will be divided into hyperplasia, breast adenosis (also divided into lobular hyperplasia period, defibrillators Victoria adenosis period and the period of fibrosis), breast cysts in three categories; Some scholars by the proliferation of breast basic organizational changes will be divided into lobular hyperplasia, fibrosis, inflammatory, cysts, epithelial hyperplasia, six types adenosis . It is precisely because of its shape On the complexity of the school and therefore the disease caused the confusion of names, such as lobular hyperplasia, chronic mastitis, fiber cystic breast disease, benign epithelial hyperplasia, adenosis, and so on. By the illness of breast duct epithelial hyperplasia of the form can be divided into four: Ⅰ level: not with duct epithelial hyperplasia, the incidence of this level for 70%; Ⅱ level: with duct epithelial hyperplasia, but not a special-shaped cells , The rate was 20 percent; Ⅲ a class: with duct epithelial hyperplasia, epithelial cells were mild atypia, the rate was 5%; Ⅲ b class: with duct epithelial hyperplasia, epithelial cells were severe atypia, the rate was 5 percent, the highest rate of grade malignant , May be malignant rate of 75% ~ 100%.
