[Muscle-localized tumorlike polyarteritis nodosa].
BACKGROUND
Systemic vasculitis presenting as a tumorlike lesion are unusual and affect mainly the uro-genital system and breast. Muscle-localized tumorlike periarteritis nodosa are scarce.


METHODS
We report localized tumorlike polyarteritis nodosa affecting the forearm muscles in a 90-year-old woman.


CONCLUSIONS
Other cases of polyarteritis nodosa localized to muscles are reviewed. This limited form has a benign clinical course and responds promptly to treatment with corticosteroids alone but relapses may occur.
