Plasma cell mastitis

Case contributed by Edgar Lorente


Breast cancer screening.

Patient Data

Age: 50 years
Gender: Female

Linear, thick, 'rod-like' calcifications in both breasts, with a symmetrical distribution. Typical appearance of plasma cell mastitis (BI-RADS 2, benign).

Predominantly fatty breast tissue. No further findings.

Case Discussion

We show a typical case of plasma cell mastitis, with thick, uniform, rod-like calcifications with linear distribution towards the nipple.  

In contrast to infiltrating ductal carcinoma, the calcifications present in plasma cell mastitis are thicker and longer, as well as more uniformly dense.

Plasma cell mastitis is a benign entity (BI-RADS 2) that does not increase the risk of cancer, so no specific follow-up is required.
