Breast Fibroadenoma the pathological manifestations of what?

The general breast fibroadenoma were found: fibroadenoma and the surrounding breast tissue boundaries clear, activities, tough texture, smooth surface. Sustained tumor round or oval, the surface often integrity of the thin fibrous capsule. When more fiber components, the cut surface gray tumor, translucent texture tough, resilient when its epithelial component rich, the cut surface Pale Pink, fine granular, or even a papillary, overseas'll texture partial Soft. Breast fibroadenoma in the light microscope, in accordance with its fibers and the growth of epithelial component level and the structure of mutual relations, divided into tube type, the week and mixed three types of pathology. (1) of the type: the proliferation of mesenchymal oppression Xianguan fibrous tissue, it elongation, bending and deformation and stromal components seem to be penetrated within the lumen. Xianguan epithelial shrink by squeezing into a flat shape. Fibrous tissue within the tumor than osteoporosis, a mucoid. (2) of the week: epithelial component and fiber ingredients mixed up together, Xianguan a round, oval or irregular in shape, fibrous tissue hyperplasia from the extrusion. Luminal epithelial cells have two components, the single cube-shaped inner or columnar epithelium, and the outer layer to the cytoplasm translucent myoepithelial. Its components can be mild epithelial hyperplasia. Tumor fibrous tissue hyperplasia, and around the Xianguan around, loose or tight, it could even be a collagen denaturation. (3) mixed: in - pipe type of peripheral and the pathological changes of the case.
