DCIS - right breast

Patient Data

Age: 40
Gender: Female

Microcalcifications are found extending in a radial fashion in the upper outer quadrant of the right breast. The magnified views are very suggestive of DCIS (later confirmed histologically).

Case Discussion

This case represents histologically confirmed DCIS with an IDC component as suspected on the ultrasound images. 

In this case the DCIS component is actually much larger than suggested on the initial mammogram. The actual extent was from the nipple radially into the periphery of the breast. The extent of the calcifications is underestimated in most cases. The microcalcifications of DCIS are sometimes incorrectly referred to as "amorphous". This means without shape or form. However, the calcifications have both shape and form, and are heterogeneous, not amorphous.

It is therefore essential to do an ultrasound during the workup of microcalcifications of the breast.
