[The liver in juvenile rheumatoid arthritis].

Hepatic involvement in juvenile rheumatoid arthritis of the systemic type (JRA) is a diagnostic challenge because of the varied clinical picture it presents. We describe a 21-year-old woman in whom JRA had started at the age of 4 years as an illness resembling familial Mediterranean fever. This long-standing illness was complicated by liver damage and needle biopsy showed massive hepatic deposition of amyloid. It is possible that this patient may have developed JRA as a complication of familial Mediterranean fever.
