RESUMO
Os autores relatam um caso de granulomatose de Wegener com insuficiência renal rapidamente progressiva que evoluiu para óbito. Os achados histopatológicos evidenciaram glomerulonefrite granulomatosa e necrose papilar renal, achados estes pouco freqüentes na moléstia. Discutem-se os diagnósticos diferenciais da granulomatose de Wegener

Three patients who developed renal papillary necrosis while receiving long-term, high-dose aspirin therapy for juvenile rheumatoid arthritis are presented. It appears that aspirin alone or aspirin in combination with other drugs is the causative agent. The incidence and biologic significance of renal papillary necrosis are insufficient to alter the use of aspirin as the drug of choice in management of JRA. It is recommended that all children with JRA be encouraged to drink ample fluids and be followed with periodic urinalysis and blood pressure measurements. Those children who develop hematuria or hypertension should be evaluated by excretory urography.
