[Pericarditis disclosing at adult age recurrent Still's disease in childhood]. / Péricardite révélatrice à l'âge adulte d'une récidive de maladie de Still de l'enfant.

A 29 year old patient with a history of juvenile rheumatoid arthritis had a recurrence 12 years later, presenting as pericardial effusion with cardiac tamponade. Cardiac tamponade is a rare complication of Still's disease. To the author's knowledge, it has never been described as the mode of presentation of adult Still's disease. The diagnostic difficulties and inefficacy of non-steroid anti-inflammatory agents are illustrated by this case.
