Infiltrating ductal carcinoma arising in fibroadenoma and associated proliferative mammary disease in a 38 years old female -a rare case report

Infiltrating ductal carcinoma arising in a fibroadenoma is a rare incidental finding. incidence is 0.002-0.0125%. women having proliferative disease without atypia have a twofold elevation in their risk for subsequent invasive breast cancer. we here present a case report in a 38 year female having fibroadenoma,intraductal papilloma and fibocystic disease of breast who subsequently developed invasive ductal carcinoma in the fibroadenoma. thus these lesions can be considered to have increased risk of developing malignancy. © journal of krishna institute of medical sciences university.
