The rash in Henoch-Schonlein Purpura is typically characterized by which finding?

• A. Symmetrical palpable purpura on the legs
• B. Maculopapular rash on trunk
• C. Petechiae on arms only
• D. Vesicular rash on face

Answer: (A)

In Henoch-Schönlein purpura, the rash comes from small-vessel inflammation (IgA-mediated leukocytoclastic vasculitis) that produces palpable, non‑blanching purpura. The classic pattern is symmetric, raised purpura on the lower legs and buttocks in children. This palpable quality and dependent distribution distinguish it from other rashes. Other patterns—maculopapular rash on the trunk, isolated petechiae on the arms, or vesicular rash on the face—don’t fit the typical presentation of this condition.
