case_images: An ultrasound-guided core biopsy of the right axilla suggested an amyloid tumor of the breast associated with moderate lymphocytic infiltrate (Figure 1A). Congo red stains supported the diagnosis of amyloidosis, and presence of AL amyloid was confirmed by immunochemistry (Figure 1B).
case_images: Renal biopsy showing amyloidosis, extensively involving glomeruli, blood
  vessels, and interstitium (H&E x400).. Abbreviation: H&E, hematoxylin-eosin.
