Familial Mediterranean Fever (FMF) is characterized by recurrent attacks of self-limited polyserositis and fever. Several types of vasculitis are associated with FMF: polyarteritis nodosa, Henoch-Schonlein purpura (HSP), and protracted febrile myalgia (PFM). We describe three cases of vasculitis in four siblings of a Sephardic Jewish family with FMF and reviewed the literature. One brother and one sister developed severe HSP with intestinal involvement while another brother developed PFM. Genetic tests in three brothers confirmed the M694V mutation on both alleles. Vasculitides may be a clinical feature of FMF with a higher familiar prevalence. MEFV mutations may act as a genetic susceptibility factor for vasculitides in FMF patients.
