Hemodialysis-associated soft tissue amyloidomas of the chest and abdominal wall.

Amyloidoma is a highly unusual presentation of amyloidosis in tumoral or nodular form. Isolated soft tissue amyloidomas in individuals with end-stage renal disease on chronic hemodialysis is exceedingly rare, particularly in the era of advanced dialysis technologies. We report the case of a 55-year-old male with end-stage renal disease due to autosomal-dominant polycystic kidney disease, on HD for over 30 years, who was found to have soft-tissue, dialysis-related (β -microglobulin) amyloidomas (DRA).

It is described classically as a type III hypersensitivity response to heterologous proteins. Its true mechanism is still unclear.
