Breast Hamartoma: Breast within Breast Sign

Abstract

Breast hamartoma is one of the rare benign lesions described. A varied histopathological type of hamartoma has been described under this heading. However the imaging findings are unable to distinguish these histopathological types, mammography and sonomammography are fairly diagnostic of this condition. A case of a 42-year-old multiparous lady with a history of lump in the left breast for duration of 2 years was discussed in present case.
