What´s Ductal Hyperplasia?
Ductal hyperplasia
Ductal hyperplasia is characterized by proliferation of ductal epithelium, resulting in increased cellularity and multi layering of ductal epithelium. The pattern of growth varies greatly from case to case leading to different types of ductal hyperplasia.
Features indicative of benign nature of the lesion includes oval nuclei with indistinct cytoplasmic border and eosinophilic rather than pale cytoplasm, arrangement of the cells in parallel bundles, presence of peripheral elongated clefts in ducts, presence of myoepithelial layer, apocrine metaplasia and absence of necrosis.
Ductal hyperplasia has been subdivided into mild, moderate and florid categories. In mild ductal hyperplasia, the epithelial thickness is
