"Mammary dysplasia" and "fibroadenoma" represent almost all benign breast disease presenting with breast lumps. Mammary dysplasia comprises variable non-specific changes of stroma and epithelium, but fibroadenoma has been classified as a benign neoplasm, although both features not uncommonly coexist. Authors performed a blind microscopic review of 660 cases of benign breast lesions and the results are as followings. 1. Only 27.9% of all cases consisted of pure fibroadenoma in contrast to 57.5% in the original diagnosis. 2. Fibrocystic disease frequently contained foci of fibroadenoma showing varied stages (68.3%), and the younger age group presented more wide areas of fibroadenoma. 3. The most common feature of the fibrocystic disease was fibrosis, followed by cystic change, adenosis and epithelial hyperplasia in order of frequency. 4. Fibroadenoma may be a form of a spectrum produced by hormonal imbalance, and better classified as a nonneoplastic lesion.
