There was hematological malignancy in 18 (29%) and solid organ malignancy in 13 (21%) cases. Thirty-one (50%) cases were immuncompromised for reasons other than malignancy. By endoscopic evaluation endobronchial lesion was seen in 2 (3%) cases, indirect tumor signs were seen in 2 (3%) cases and signs of infection were seen in 11 (18%) cases. Fortyseven (76%) cases were endoscopically normal. Acid-fast bacilli (AFB) direct examination was positive in 3 (5%) cases. In 4 (6%) cases mycobacterial culture was positive, Mycobacterium tuberculosis-polymerase chain reaction (PCR) was also positive in these four cases. Examination of Gram-stained smears for bacteria was associated with infection in 14 (23%) cases. Bacteriologic cultures were positive for single potential pathogen in 10 (16%) cases, and for mixed pathogens in 7 (11%) cases for a total number of 17 (27%). Fungal cultures were positive in 3 (5%) cases all of which had hematological malignancy. As a result in 24 (39%) cases microbiological agent of infection is determined: in four mycobacteria, in 17 bacteria other than mycobacteria and in three fungi.TurkishBronchoalveolar Lavage FluidBronchoscopyFemaleHumansImmunocompromised HostLung DiseasesLung Diseases, FungalMaleMiddle AgedMitosporic FungiMycobacterium tuberculosisOpportunistic InfectionsPredictive Value of TestsTuberculosis, Pulmonaryacid fast bacteriumadultagedarticlebacterium culturecontrolled studyendoscopyfemalefungushumanlung infectionlung lavagemajor clinical studymaleMycobacteriumMycobacterium tuberculosisArticle
