[Problems in diagnosis of localized Wegener's lung granuloma]

A case of the localized Wegener's lung granuloma diagnosed with an open lung biopsy in alive patient is presented. Despite the treatment with cyclophosphamide and corticosteroids patient died--probably due to postoperative bacterial complications. This case was discussed on the background of other reports on this rare form of Wegener's lung granuloma frequently simulating neoplastic process. The authors did not find a description of similar localized Wegener's lung granuloma in the Polish literature.
