Breast Amyloidosis: A Case Report and Literature Review

Amyloidosis is an uncommon disorder characterized by extracellular accumulation of misfolded proteins in tissues. We report a unique case of localized breast amyloidosis in an asymptomatic 56-year-old woman with systemic lupus erythematosus, presented as suspicious microcalcifications without mass on mammography. Vacuum biopsy confirmed amyloidosis, producing the typical apple-green birefringence under polarized light after staining with Congo-red. Further workup and follow-up to exclude development into systemic amyloidosis or hematologic malignancy is recommended. If negative, the prognosis is very good, thus no further treatment is needed. A brief review of the literature revealed more about the typical findings and recommended management
