Breast by the pathological manifestations of illness

Breast lesions by sick specimens for the general, the lesions showed diffuse or limitations, hard and tough and dense texture, color yellow-white or grey, no capsule, section there are a number of different size translucent particles such as cystic hyperplasia can be seen small Cysts wall mostly smooth capsule containing yellow-green or brown viscous liquid, and some are granular substances or to intracavitary of papillary outstanding. By illness in breast pathology, on the one hand for the performance of the cystic ductal breast expansion, ranging from the size of the cyst formation of the same performance as ductal epithelium have varying degrees of papillary hyperplasia, lobular and lobular of fibrous tissue to various degrees Hyperplasia. Because breast by sick morphology complex, its histologic classification methods varied. For scholars in accordance with the volume and structure of the breast morphological abnormalities will be divided into breast tissue hyperplasia, breast adenosis (also divided into lobular hyperplasia period defibrillators Victoria adenosis period and the period fibrosis), Breast Disease three categories; Some scholars on the basic structure of mammary gland hyperplasia change will be divided into lobular hyperplasia, and fibrosis and inflammation, cysts, epithelial hyperplasia, adenosis six types . It is precisely due to its shape The complexity of the study, the disease that led to the naming of the confusion, such as lobular hyperplasia, chronic mastitis, fiber cystic breast disease, benign epithelial hyperplasia, such as adenosis. By illness by breast ductal epithelial hyperplasia patterns can be classified into four classes: class Ⅰ: without ductal epithelial hyperplasia, the incidence of this level of 70 per cent; grade Ⅱ: with duct epithelial hyperplasia, but not to show heterotypic cell , 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 malignant transformation of this class , may be malignant rate of 75% ~ 100%.
