Cutaneous extravascular necrotizing granuloma in a patient with Takayasu's aortitis.

Cutaneous extravascular necrotizing granulomas (Churg-Strauss granulomas) have been noted in several systemic diseases, most often those producing or associated with systemic vasculitis. A young man with the clinical and histopathologic features of Takayasu's aortitis developed typical extravascular necrotizing granulomas of the skin. Takayasu's aortitis, like allergic granulomatosis and Wegener's granulomatosis, is a granulomatous vasculitis syndrome associated with the cutaneous Churg-Strauss granuloma.
