Fibroadenolipoma of the breast.

Fibroadenolipoma is a well recognised but unusual benign tumour of the breast. It is a circumscribed lesion composed of fat and other breast tissues which may be normal or which may show various benign changes. The presence of smooth muscle has been recorded but was not found in our cases. A series of eight cases is described, occurring over a period of 10 years in a series of 20 000 mammograms. Radiological and pathological correlation is made and histological changes are described. Our findings are compared with other reviews in the literature. The lesions are usually diagnosed radiologically.
