An Unusual Case of Henoch Schönlein Purpura Presenting as Mononeuritis Multiplex

IgA vasculitis [Henoch Schönlein Purpura (HSP)] is characterized by leukocytoclastic vasculitis involving the small vessels with deposition of immune complexes that contain IgA. Clinical signs include purpura, arthralgia, glomerulonephritis and gastrointestinal involvement. HSP with nervous system involvement is very uncommon. We report a 12 year old boy with IgA vasculitis who presented with typical rash and Mononeuritis Multiplex and responded well to steroid therapy. HSP presenting as Mononeuritis Multiplex has rarely been reported in children. Clinicians must know of this rare complication of HSP which, when present, may be well managed with steroids.
