Abstract
A case of Wegener's granulomatosis that was associated with an intractable pharyngeal ulcer is herein reported. The measurment of Cytoplasmic-Anti-Neutrophil-Cytoplasmic-Antibody (C-ANCA) was found to be useful in making the final diagnosis of Wegener's granulomatosis in this case. This disease should thus be considerd in the differential diagnosis of intractable pharyngeal ulcers. In cases of pharyngeal ulcers where a final diagnosis can not be obtained even after performing both biopsy and blood examinations, generally steroid therapy appears to be necessary in order to control the symptoms of Wegener's granulomatosis.
