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.
