plasma cell mastitis
Plasma cell mastitis is a benign breast condition which represents calcification of inspissated secretions in or immediately adjacent to ectatic benign ducts.
It is typically seen in older women (e.g. >60 years of age).
It is thought to represent aseptic inflammation of the breast from extravasation of intraductal secretions into periductal connective tissue.
Plasma cell mastitis has a characteristic appearance. Calcifications are thick, linear, rod-like or cigar-shaped. Calcifications can be up to 10 mm long. They tend to be bilateral, often symmetrical in distribution and oriented with long axes pointing toward the nipple. Branching may sometimes be seen.
Treatment and prognosis
It is a benign entity and there is no increased risk of malignancy .
