Polyarteritis nodosa (PAN) is a medium vessel vasculitis with necrotising vascular changes along with multisystemic involvement. Due to variable initial presentations, diagnosis of systemic PAN in children requires a comprehensive work up. In addition, systemic PAN needs an aggressive therapy. Mycophenolate mofetil is an emerging newer alternative for the treatment of PAN. We report a case of childhood systemic PAN who initially presented with subtle signs like reduced sensation over lateral foot, non-deforming arthritis and multiform rashes. After comprehensive aetiological work up, nerve biopsy and supporting evidence clinched the diagnosis. Vasculitis in children presenting with benign subtle signs is sometimes a diagnostic challenge to clinicians. Our case highlights the importance of lateral thinking while dealing with non-specific multisystemic signs. Evidence of successful treatment of PAN with mycophenolate mofetil is gradually being built up. It is also described to result lower relapse and increased treatment free survival rate.
