title: Systemic reactive amyloidosis caused by hepatocellular adenoma. A case report.
abstract: Systemic reactive amyloidosis caused by non-malignant tumors seems to be extremely rare. In the present paper a 39-year-old female with systemic reactive amyloidosis caused by a hepatocellular adenoma is described. The patient had a history of using contraceptive drugs. She had a pronounced nephrotic syndrome, a renal biopsy showing reactive (AA) amyloidosis, and a bone scintigraphy (99mTc methylene diphosphonate, TcMDP) showing an increased uptake in soft tissues. Removal of the adenoma was followed by a gradual resolution of the nephrotic syndrome and a normalization of the bone scintigraphy. The tumor was histologically a mixture of focal nodular hyperplasia and liver cell adenoma.
