Epithelial hyperplasia

Usual ductal hyperplasia, also known as epithelial hyperplasia, is a benign proliferation of normal cells in breast ducts and lobules.

breast ducts and lobules usually lined by a single outer layer of myoepithelial cells and a single inner layer of epithelial/luminal cells
in usual ductal hyperplasia, there are an increased number of myoepithelial and luminal cell types that fill and distend ducts and lobules²
no epithelial cell atypia

Radiographic features

No specific imaging findings.

Treatment and prognosis

No treatment is required. Usual ductal hyperplasia confers a 1.5-2x increased risk for subsequent breast cancer ^{1, 3}, which may be slightly higher in those with a family history of breast cancer ⁴.
