Figure 1: Top left: H and E, stain: Marked fiber size variation with frequent angulated atrophic fibers. There is no active degenerating/regenerating muscle fiber/inflammation. Top right: Congo red stain: prominent amyloid deposit in the connective tissue and vascular wall. Bottom left: Polarized amyloid deposits with Congo red stain: Muscle. Bottom right: Bone marrow biopsy: 25% of the biopsy is involved by a diffuse and interstitial lymphoplasmacytic infiltrate. Magnification ×175
