Breast
(1) Juvenile papillomatosis A term referring to the appearance of a ductal hyperplasia with epithelial proliferation and clustered cyst formation, usually seen in girls and premenopausal women, presenting as localized multinodular masses simulating fibroadenoma

Endometrium A popular term for the histologic changes of cystic glandular hyperplasia which is seen in the menopausal endometrium, associated with increased estrogen from persistent follicles, granulosa-theca cell tumours of the ovaries, adrenocortical hormones or related to exogenous estrogen therapy.

When the cystic glandular hyperplasia is particularly exhuberant, the resulting tissue is termed endometrial polyp, here seen by ultrasonography

Polyps
