INTRODUCTION: Fibroadenoma is the most common benign tumor of the female breast with the highest incidence before age 30. Fibroadenoma may be associated with fibrocystic changes, proliferative epithelial changes, and extremely rarely, with non-invasive and invasive cancer. CASE PRESENTATION: We present a rare case of a 39 years old female with invasive ductal carcinoma arising within fibroadenoma. CONCLUSION: There is a low percentage of fibroadenomas harboring carcinoma; however, all breast lumps should be seriously managed; extirpation and histological examination is recommended.
