Breast Hamartoma-Mammogram

There is presence of a  large thin walled well defined encapsulated lesion with heterogeneous density in retroareolar region of right breast,extending to both outer and inner periareolar region. It consists of both fat and soft tissue density. Globular homogeneous soft tissue density is noted within the rim on upper inner aspect of the lesion. No  intralesional calcification is noted. No skin thickening or nipple retraction is noted. Possibility of benign hamartomatous lesion (fibroadenolipoma). It results from a benign proliferation of fibrous, glandular, and fatty tissue (hence fibro-adeno-lipoma) surrounded by a thin capsule of connective tissue. All components are found in normal breast tissue (hence the term hamartoma). Also called as BREAST WITHIN BREAST APPEARANCE. Case submitted by Dr Swati Shah, FRCR.
