A 40-year-old man had a pathologically proved limited form of Wegener's granulomatosis complicating recurrent and massive hemoptysis from his cavitary pulmonary lesion. Of significant interest and clinical importance is the unusual location of the patient's pulmonary lesion, occurring in the posterior segment of the right upper lobe. This experience demonstrates that the location of the pulmonary nodule is not necessarily useful in distinguishing Wegener's granulomatosis from infectious granulomatosis, particularly tuberculosis.
