Development of acute Henoch-Schönlein purpura subsequent to endodontic treatment.
BACKGROUND
Henoch-Schönlein purpura (HSP) is an inflammatory disorder of unknown origin that is characterized by IgA-dominant immune complexes in smaller blood vessels. It results in a triad of symptoms, including a purpuric rash on the lower extremities, abdominal pain or renal involvement, and arthritis. Any of the triad may be absent, however, which often leads to confusion in diagnosing the condition. Cases of acute HSP developing subsequent to dental treatment have not been previously reported in the dental literature.


METHODS
This study reports the unusual case of a 14-year-old female who developed acute HSP following endodontic treatment.


CONCLUSIONS
Treatment for this condition is supportive and children affected by this disorder need close follow-up of their renal status.
