Secondary amyloidosis in progressive systemic sclerosis.

Progressive systemic sclerosis (PSS) is a connective tissue disease that may affect many organs, including the kidneys. It is quite rare to see secondary amyloidosis due to PSS. We present a patient with a 9-year history of PSS who developed nephrotic syndrome, and whose renal biopsy was compatible with secondary amyloidosis. He died from massive upper gastrointestinal bleeding caused by oesophageal telangiectasia.
