Recurrent breast amyloidosis associated with Sjögren's syndrome: A case report with description of the radiologic-pathologic correlation.

We describe the case of a 41-year-old woman with primary Sjögren's syndrome (SS) who presented multiple recurrences of breast amyloidosis. Each recurrence of breast amyloidosis showed different sonographic features, potentially mimicking malignancy. We briefly discuss the possible cause of this variability in imaging features based on the radiologic-histologic correlation.
