Otolaryngologic manifestations of systemic vasculitis.

Systemic vasculitis is a heterogeneous group of diseases of various aetiologies and manifestations. In general, the clinical results derive from ischemia caused by vascular inflammation, which depends on the organ affected. Such vasculitis cases are classified according to the classification of the Chapel Hill conference. They can present with relative frequency as ENT manifestations in both their debut and throughout their evolution. Consequently, the ENT specialist should include them in the differential diagnosis in patients with ENT manifestations that are difficult to control or of atypical presentation. Our objective was to review the most common ENT clinical signs and symptoms in each of these diseases.
