Primary breast amiloidosis

Abstract

Breast amyloidosis can be primary or part of a systemic disease. The primary tumor amyloid represents 12.8% of the cases of amyloidosis, and the primary breast amyloidosis corresponds to 0.5% of the cases of amyloidosis, representing a very rare entity. It may present as a breast mass or asymptomatic in the form of asymmetry or microcalcifications. It can also mimicking malignancy and in some cases it is associated with a concomitant carcinoma. The treatment of primary amyloidosis of the breast is the surgical removal of the suspected area, a fact that is associated with good outcome. We describe a case of primary breast amyloidosis, discussing the multiple factors related to the diagnosis, differential diagnosis, management and follow up.
