Juvenile Papillomatosis of the Breast: A Benign Proliferative Lesion of Uncertain Precancerous Potential

Juvenile papillomatosis is a benign proliferative lesion, which may include atypical duct hyperplasia, that occurs most often in women 15 to 30 years of age. About one third of the patients have a positive family history of breast cancer. Breast carcinoma only rarely has been detected in patients with juvenile papillomatosis but long-term follow-up, which is not yet available, will be necessary to assess the precancerous risk of this condition.
