Reye's syndrome in a child on long-term salicylate medication.

A case of Reye's syndrome in a four-year-old child on long-term salicylate medication for rheumatoid arthritis is reported. Severe fatty changes of the liver, lipid vacuolation in the renal proximal tubules, and severe brain oedema were the prominent postmortem findings. Symptoms of a trivial infection and vomiting just before death added to the resemblance of this case to Reye's syndrome.
