    Abstract:
    We report two cases of gastrocnemius muscle vasculitis revealing Crohn's disease. Gastrocnemius muscle biopsy evidenced a necrotizing vasculitis resembling panarteritis nodosa in one case; a nonnecrotizing vasculitis was found in the other case. Neither of the patients had systemic vasculitic involvement, and the muscle disease resembled calf muscle-located panarteritis nodosa. Our literature review shows five cases of calf-located myalgia occurring during Crohn's disease characterized by heterogenous histopathological findings including vasculitic and myositic lesions. Thus, faced with calf-located myalgia with vasculitis or myositis, a search for Crohn's disease is probably necessary to determine precisely the frequency and the etiopathogenic mechanisms of this association.
