Cutaneous vasculitis in children is rare. Causes of cutaneous vasculitis are varied and are typically differentiated by the affected vessel size. A skin biopsy remains the gold standard for diagnosis but other causes for vasculitis, including systemic conditions, should be considered. This article discusses the childhood conditions commonly presenting with cutaneous vasculitis (leukocytoclastic vasculitis, cutaneous polyarteritis nodosa), biopsy recommendations and findings, and management and potential differential diagnoses, and includes a brief summary of other diseases that may include cutaneous symptoms as a constellation of other systemic findings.
