Nasopharyngeal tumour in hypersensitivity vasculitis.

Hypersensitivity vasculitis refers to a large and heterogeneous group of clinical syndromes that have in common the predominant involvement of small vessels, especially in the skin. But any organ can be involved with its associated specific clinical and pathologic manifestations. As involvement of the upper airways has not previously been reported, a case of vasculitis associated with a nasopharyngeal tumour is presented. The possible etiology and relation to other diseases in the upper respiratory tract, especially Wegener's granulomatosis, is discussed.
