The fibroadenoma (FA) is a common tumor of the breast that usually occurs in the second or third decade of Ufe. The carcinomas of the breast rarely arising within a FA, with around 200 cases reported in the literature. We report the presence of DCIS within a FA on three female patients of 31, 45 and 47 years oíd. Due to the presence of microcalcifications in two patients and the suspicion of an intraductal papilloma in the third, they underwent a partial mastectomy with the consequent finding of DCIS inside a FA. In two cases there were extensive DCIS in the adjacent breast parenchyma and finally they underwent a total mastectomy. We recommend a strict follow up in women with FA from the fourth decade of life. In patients with proliferatives breast lesions or DCIS that simultaneously presenting a FA, we recommend surveillance of FA or remove it at the same time of the resection of DCIS.
