Ductal carcinoma in situ

Case contributed by Garth Kruger
Diagnosis certain


Right breast mass.

Patient Data

Age: 35 years
Gender: Female

Ultrasound image in the area of the palpable mass. The areola is superior almost in the center of the image. This is subareolar breast tissue. The image was interpreted as normal and no further work up was done.

The mass lesion enlarges and the patient returns 8 months later. 


This is the ultrasound image (unfortunately badly cropped to exclude data) of the same area. There is now a distinct lobulated mass lesion. At this stage mammography was added (image below).

Same day as second ultrasound


On the first image there are calcifications visible in the ducts extending in a radial fashion from the posterior aspect of the areola.  This is a very good image of the ultrasound of DCIS.

Case Discussion

The final diagnosis was multifocal breast carcinoma with axillary metastases.
