title: Histological and needle-biopsy studies of juvenile mastopathy.
abstract: The cytomorphological and histological aspects of benign breast tumours found in the course of 1000 needle-biopsies in 119 young females (under 20 years old) has been outlined. According to the author epithelial-proliferation which not only appears alarming at this stage but is also on the edge of malignancy is quite frequent at this age. However, based on thorough follow-up examinations he warns of too quick and unfavourable judgement regarding epithelial-proliferation as none of the 119 cases cited have become malignant through the years observed. The found the diagnostic value of needle-biopsy especially useful in younger patients and suggests its more habitual use in everyday practice.
