Systemic AA amyloidosis induced by oral contraceptive-associated hepatocellular adenoma: a 13-year follow up

We report a case of a woman who showed hepatic and renal AA amyloidosis with a liver adenoma associated with the use of oral contraceptives. A nephrotic syndrome secondary to the renal amyloidosis underwent complete remission 7 years after the withdrawal of oral contraceptive therapy. Twenty-nine months after the initial presentation, the patient was admitted with acute upper abdominal pain and abdominal tenderness. The abdominal ultrasound revealed a subphrenic fluid collection, and a presumptive diagnosis of a ruptured hepatic adenoma was made. The liver adenoma diminished from 8 cm to 1 cm over a 13-year follow up after the discontinuance of oral contraceptive therapy.
