Clinical and histological resolution of systemic amyloidosis after renal cell carcinoma removal.
This report describes the case of a 62-year-old woman with systemic amyloidosis involving the kidneys and digestive tract, consecutive to a renal cell carcinoma. Within 3 years after tumor removal, both the nephrotic syndrome and protein loss enteropathy regressed. Histological examination showed the disappearance of the potassium permanganate-sensitive deposits within the digestive tract. This indicates that clinical remission of systemic amyloidosis may be associated with morphologic disappearance of amyloid deposits.
