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.
