Henoch-Schönlein purpura (HSP) is an immunoglobulin A (IgA)-mediated multisystem vasculitis commonly affecting children under 10 years of age. Although diagnostic criteria exist, making a diagnosis is often difficult as this condition can present atypically in adults. We discuss a 22-year-old female with a delayed diagnosis of HSP, resulting in significant anxiety and distress. Our patient's symptoms improved with analgesia and corticosteroids, which were initiated upon diagnosis and she experienced two mild, self-limiting relapses over two years following symptom resolution. Our case illustrates that an integrated multidisciplinary approach is needed to effectively diagnose, safely manage and monitor patients presenting with HSP. Although self-limiting in nature, HSP has the potential to manifest into life-threatening conditions such as end-stage renal failure, which stresses the importance of early diagnosis and management.
