Diagnosis of Wegener's granulomatosis by transbronchial biopsy.

We performed transbronchial biopsies in a patient with a large cavitary lung lesion and obtained tissue diagnostic of Wegener's granulomatosis. Fiberoptic bronchoscopic examination with transbronchial biopsy may be indicated as the first diagnostic test in the evaluation of patients with suspected Wegener's granulomatosis.
