[Histological findings on the relation between elastosis and breast neoplasms and dysplasia]

Connective tissue changes with particular reference to elastosis in malignant and dysplastic breasts are studied. Hyperelastosis was closely associated with carcinoma particular with scirrhous type also in the perineoplastic area; on the contrary the percentage of the phenomena in benign displastic disease is significantly low. Elastosis was located around carcinomatous tissue, mammary neoplastic ducts and also around veins and as scattered foci in the stroma. The site of production of elastic fibers is discussed. Elastosis accompanying carcinoma is considered more than a simple association but its prognostic significance has not an absolute value.
