Subcutaneous nodules on the buttocks as a manifestation of dialysis-related amyloidosis: a clinicopathological entity?
While β2-microglobulin amyloidosis occurring in patients undergoing long-term dialysis is frequently associated with joint involvement, skin lesions have rarely been encountered. We report a 57-year-old man with extensive subcutaneous amyloid deposition forming large nodules on the buttocks; the patient had been on maintenance dialysis for 28 years. Although this condition is rare, a review of the literature indicates that the majority of such lesions occur around the buttock region.
