This image depicts an anterior view of the lower legs of an 8-year-old patient, who presented with numerous erythematous lesions, which had been identified as anaphylactoid purpura, also known as Henoch–Schönlein purpura (HSP). The precise cause for this reaction is unknown, but HSP involves an inflammatory process of small blood vessels, including the deposition of immune complexes, specifically antibody IgA. This reaction is self-limited, resolving itself within a few weeks. However, statistics show that there can be a secondary onset in one-third of cases, with 1% of cases including permanent kidney damage.
