[Juvenile cutaneous polyarteritis nodosa associated with streptococcal infection].

Polyarteritis nodosa is a rare vasculitis of small and medium arteries. It can occur in a systemic form with multi-organ involvement, or as a limited form confined to the skin, muscles, joints and peripheral nerves called cutaneous polyarteritis nodosa. Both forms are rare in adults and even more in children. The caues of this vasculitis remain unknown but some viruses and bacteria have been implicated, specially, Streptococcus. We present the case of a 6-year-old child who developed cutaneous polyarteritis nodosa following a probable streptococcal infection.
