Summary

Cutaneous polyarteritis nodosa in children presents as painful skin nodules and arthritis. Early diagnosis via biopsy and treatment with corticosteroids, alongside checking for streptococcal infection, ensures a good prognosis.

Area of Science:

  • Pediatric Rheumatology
  • Dermatology
  • Vascular Inflammation

Background:

  • Cutaneous polyarteritis nodosa (cPAN) is a rare vasculitis affecting children.
  • It typically follows a benign, chronic course without systemic organ involvement or hypertension.
  • This study details a pediatric case and reviews existing literature.

Observation:

  • A 3-year-old boy presented with painful, edematous skin nodules on extremities and trunk.
  • Symptoms included fever and arthritis.
  • Laboratory tests revealed an acute phase response and elevated antistreptolysin titer.

Findings:

  • Skin biopsy confirmed necrotizing arteritis in the lower dermis with mixed neutrophilic and eosinophilic infiltrates.
  • The patient showed a positive response to corticosteroid treatment.

  • Diagnosis was consistent with cutaneous polyarteritis nodosa.

    • Implications:

    • Pediatric cPAN requires prompt diagnosis through skin biopsy.
    • Evaluation should include screening for streptococcal infections.
    • Corticosteroid therapy is effective for managing pediatric cPAN.
