Irregular hypoechoic masses in breast do not always indicate malignancies. These lesions were assessed as BI-RADS Category 4a-to-4c suspicious malignancy on ultrasonography, resulting in US-guide biopsy. 1. There were many kinds of benign or borderline breast diseases representing irregular hypoechoic masses that can mimic carcinoma on ultrasonography.  2. Careful US examination, history taking, and biopsy could help to differentiate them from malignancies.  

Benign or bordeline breast lesions into 4 groups - Iatrogenic or trauma-related breast lesions Foreign body reaction Fat necrosis Fibrotic scar   - Proliferative disease - Benign breast tumors - Inflammation Abscess Idiopathic granulomatous lobular mastitis Diabetic mastopathy Sclerosing adenosis Apocrine metaplasia Fibrocystic change Intraductal papilloma Fibroadenoma
