Radial scar

A radial scar of the breast, formally radial scar of the breast,[1] is a benign breast lesion that can radiologically mimic malignancy, i.e. cancer.[2]

SpecialtyGeneral surgery

Radial scar is associated with atypia and/or malignancy and may be an independent risk factor for the development of carcinoma in either breast.[3]

Diagnosis

Radial scars are diagnosed by a microscopic examination of excised tissue, i.e. they are diagnosed by pathologists based on their histomorphology.

Histomorphology

Radial scars are spiculated masses characterized microscopically by a sclerotic appearing (i.e. scar like) center with peripheral entrapped normal breast ducts and lobules.[3]

Management

The presence of a radial scar on imaging mandates a percutaneous core biopsy for histologic diagnosis. Excisional biopsy is usually recommended for radial scar, although it has been argued that core biopsy evaluation and surveillance may be appropriate in selected patients. [3]
