Benign sclerosing lesions of the breast

Benign sclerosing lesions of the breast comprise primarily sclerosing adenosis and radial scar/complex sclerosing lesions (RS/CSL). Other benign lesions which may become fibrosed and malignant tumours frequently associated with a schirrous reaction, may enter their differential diagnosis either radioloigcally or on pathological examination. This review focuses on the pre-operative diagnosis and operative pathology of these lesions with particular reference to their prognosis and recent trends in their management.
