[Does rheumatic pleuresy exist?].

The authors report the case of a 20 year-old young man with old rheumatic heart disease in whom suddenly occurred sero-fibrinous pleurisy with fever. The usual cause of pleurisy, e.g. tuberculosis, were eliminated. On the other hadn, there was considerable evidence, including lengthening of the P-R interval, and raised anti-streptolysin titer at 1920 units, which suggested recurrence of rheumatic fever. The relationship between this disease and sero-fibrinous pleurisy is then discussed.
