Background
The normal glandular tissue is made up of ducts,
terminal ducts,
and acini and is supported by fibrous tissue.
Most breast lesions arise from the duct-lobular system,
involving the epithelium,
and so breast cancer is the most common malignancy.
But many other entities,
either benign,
or malignant may appear within the breast.
Nonepithelial lesions are rare,
and may be found arising in structures other than duct-lobular system or by infiltration of the breast by different cells or substances or nearby structures.
Imaging findings pose a challenge in diagnosis.
We review different lesions appearing within the breast,
but with an origin different from duct-lobular system,
as well as recommendations for clinical practice.
