Imaging of fibroadenoma: Be careful with imaging follow-up.

The present letter to the editor is related to the study titled, "Preoperational diagnosis and management of breast ductal carcinoma in situ arising within fibroadenoma: Two case reports." Fibroadenoma is the most common benign mass lesion in young females. Based on this study showing that malignancy can develop on fibroadenomas, we want to emphasize that careful sonographic follow-up of fibroadenomas should be done and that each lesion should be followed carefully and separately in cases with multiple fibroadenomas. Additionally, we want to emphasize the critical role of sonographic examination in diagnosing fibroadenoma, the importance of correctly defining benign and malignant sonographic findings, and which lesions should be followed up sonographically and which lesions should be evaluated histopathologically.
