Cutaneous polyarteritis nodosa in a 7-year-old boy: difficulties in diagnosis.

Vasculitides are a diverse group of diseases. The potential diversity of their clinical symptoms requires the exclusion of other systemic connective tissue diseases, infectious diseases or malignancies. Due to similar clinical manifestations, comprehensive differential diagnosis is needed. This paper presents the case of a boy in whom polyarteritis nodosa, early stage of Behçet's disease or autoimmune/autoinflammatory syndrome induced by adjuvants was suspected following initial diagnostics. He was ultimately diagnosed with cutaneous polyarteritis nodosa.
