title: [Pathology of benign tumorous diseases of the mammary glands (author's transl)].
abstract: Among the large number of mammary biopsies undertaken today, benign diseases and marginally normal types occupy a considerable place. Of these, those which are considered prestages of malignant tumors, simulate malignant tumors and cause difficulties in differential diagnosis (intraoperative section) are of great importance. In childhood, infantile hypertrophies must be thought of macromastia in precocious puberty, puberal macromastia in puberty; in women, of forms of chronic mastitis in the presence of retention of secretion and periductal inflammation. The best known is the fibroadenoma in the region of which Cystosarcoma phyllodes and even a lobular carcinoma in situ may develop. Undoubtedly chronic cystic mastopathy is of particular prognostic significance. Less than 5% of all forms of mastopathy are premalignant diseases.
