Which feature is commonly seen in benign breast masses?

• A. Macrolobulations
• B. Microcalcifications
• C. Internal vascularity
• D. Irregular margins

Answer: (A)

Benign breast masses often have a smooth, well-defined contour, and a gently lobulated outline is a common presentation. Macrolobulations describe this lobulated margin, which you frequently see with benign lesions like fibroadenomas. The overall shape remains organized and non-spiculated, helping differentiate it from cancers that tend to have irregular, infiltrative, or spiculated margins.

Microcalcifications are more a mammography concern and, while they can appear in benign conditions, are not a typical ultrasound feature that defines a benign mass; their presence raises suspicion rather than reassurance.

Internal vascularity can be seen in both benign and malignant lesions on Doppler, but it’s not a defining feature of benign masses and is less specific.

Irregular margins strongly suggest malignancy, so that characteristic would not be typical of a benign mass.
