Shoulder pad sign and wrist and hand amyloid deposits in a patient with beta₂-m amyloidosis

(A) Bilateral shoulder pads in a patient with beta₂-microglobulin amyloidosis who was receiving long-term hemodialysis.
(B) Fixed flexion contractures of the fingers due to beta₂-microglobulin amyloid deposits in the hand of a patient receiving long-term hemodialysis. Amyloid deposits, appearing as soft tissue fullness around the wrist, resulted in carpal tunnel syndrome and atrophy of the thenar muscle.
