The purpose of this study was to present the clinical courses and histologic findings of 4 children with cutaneous vasculitis characterized by tender cutaneous nodules and fever in the absence of major organ involvement. We conducted a retrospective chart review of 4 patients with cutaneous vasculitis followed up for a mean of 68 months (range, 12-114 months). The patients included 3 boys and 1 girl (ages at onset, 2-10 years). Clinical and laboratory manifestations included tender erythematous cutaneous nodules (n=4/4), fever 39°C or higher (4/4), nondeforming arthritis (3/4), leukocytosis and elevated erythrocyte sedimentation rate (4/4), positive antinuclear antibodies (1/4), and elevated streptococcal enzymes (3/4). Skin biopsy results showed inflammation of medium-sized cutaneous arteries with a mixed inflammatory cell infiltrate consistent with cutaneous polyarteritis nodosa (4/4). Patients were treated with prednisone with good initial response, but exacerbation occurred once prednisone was tapered. Additional medications given were methotrexate (2/4), dapsone (2/4), colchicine (1/4), and cyclophosphamide (1/4). One patient is in clinical remission after 48 months of disease; the others have continuing disease that requires treatment. Patients with evidence of streptococcal infection received oral penicillin prophylaxis; two of the three patients had recurrent attacks of vasculitis despite penicillin. No patients have developed major organ system involvement after 12 to 114 months of follow-up. Cutaneous polyarteritis nodosa in children is a recognizable entity characterized by painful nodules, fever, absence of major organ involvement, and chronic or recurrent course. Patients should be screened for streptococcal infection and treated with antibiotics when needed.
