Histopathological Study on Mammary Dysplasia

Abstract

A light microscopic study of breast tissue specimen from 102 cases of mammary dysplasia collected during a period of 1974 to 1978 at Seoul National University Hospital was carried out. These cases were classified in to four subgroups of mammary dysplasia; fibrosis (6,1 cases), adenosis(23 cases), cystic disease(7 cases) and epithelial hyperplasia(8 cases). The mean age of the respective subgroups were as followings; fibrosis 35:t7.7 (SO) years, adenosis, 29. 7Jc7.1 years, cystic disease ,11. 11: 16. 4 years, and epithelial hyperplasia, 33. 61: 12. 7 years. The much higher incidence of fibrosis in our study reflects we gave the emphasis to the most prominent component for the pathologic classification. Though we had tremendous attention to the epithelial hyperplasia concerning the development of carcinoma, no suggestions were made here due to sparsity of cases and follow-up long term studies are recommended to evaluate their relationship.
