A case of eosinophilic granuloma of the lung in a 24 years old male is presented. The initial manifestations were hemoptysis and cough. During hospitalization the bronchoscopy was performed, which revealed granuloma in the right bronchus. Computer tomography showed tumour in the right bronchus, without pulmonary changes characteristic for histiocytosis X. The granuloma was removed by bronchoscopy, but control examination performed after three months showed the residue. Once again residual tumor was removed by bronchoscopy and oral steroids were ordered. Unfortunately the next local residue was observed and the residual tumour was finally removed by thoracotomy. Now patient is free of symptoms.
