[A diagnosis of Wegener's granulomatosis in a 14-year-old patient].

The paper describes a case of Wegener's granulomatosis with upper airway and lung involvements in a 14-year-old patient. Cavernous pulmonary tuberculosis was presumptively diagnosed during planned examination. The diagnosis of Wegener's granulomatosis was established by examining the materials obtained during marginal resection of the lung. The clinical and laboratory indices and histological findings of the biopsy specimens taken during open lung biopsy were considered.
