Amyloid Tumor of Breast in Multiple Sclerosis Patient.

Amyloidosis is characterized by the extracellular accumulation of abnormal fibrillar proteins in various tissue and organs of the body. Systemic or localized involvement can be seen in various organs, often depending on the underlying disease such as plasma cell myeloma or chronic inflammatory and autoimmune diseases. Amyloid deposition in the breast is rare and may present similar appearance to areas of fat necrosis with fibroelastotic stromal changes in the breast. The amyloid tumor in the breast presented in a 49-year-old female patient diagnosed with multiple sclerosis is a good example of this. Therefore, since amyloid deposition in the breast is an entity that should be kept in mind, the case was deemed worth presenting. [ABSTRACT FROM AUTHOR]
