Systemic AA amyloidosis is a rare complication of benign tumours. This report describes a patient with hepatoceliular adenoma associated with reactive AA amyloidosis. He had a nephrotic syndrome with deteriorating renal function and an increase of serum concentrations of acute phase proteins, mainly Creactive protein. Resection of the tumour was followed by improvement in renal function and a marked decrease ofthe serum concentrations of acute phase proteins.AA amyloidosis is usually observed during chronic infectious or inflammatory processes or of malignant neoplasia.' The association of a benign tumour with localised and/or systemic AA amyloidosis has been rarely described.2" We report the case of a man with systemic, mainly renal, AA amyloidosis induced by a liver cell adenoma. Surgical resection of the tumour was followed by an improvement in renal function and a decrease of the serum concentrations of acute phase proteins.
