Henoch-Schönlein Purpura: A Case Report and Review of Literature

Henoch-Schönlein purpura (HSP), or anaphylactoid purpura, is an acute, self-limited small-vessel vasculitis commonly affecting children aged 3-10. It features a classic tetrad: palpable non-thrombocytopenic purpura, abdominal pain, polyarthralgia, and renal involvement. While the prognosis is generally favorable, long-term outcomes depend on renal involvement. This report describes a two-year-old boy with a two-week history of erythematous purpura, initially on the lower extremities and spreading to other areas, accompanied by painful, pruritic rash, arthralgia, and edema. A clinical diagnosis of HSP was made, and the patient was treated with topical dexpanthenol and oral paracetamol. This case highlights the importance of recognizing HSP, understanding its manifestations, and guiding treatment and long-term management. Further research is needed to clarify aspects of its pathogenesis, treatment, and prognosis.
