| Summary: | Background/Aim. Sarcoidosis is a multisystem infmammatory disease of unknown
etiology, with the lungs and intrathoracic lymph nodes the most commonly
involved. The aim of this study was to assess the contribution of
conventional transbronchial needle aspiration (TBNA) cytology in the
diagnosis of sarcoidosis presenting as mediastinal/hilar lymphadenopathy.
Methods. In this retrospective study, 58 patients with suspicion of stage I
and II sarcoidosis underwent first flexibile, and then, a rigid bronhoscopy,
during which TBNA of mediastinal or hilar lumph node with a 19 gauge (G)
needle was done. Material from the needle was put on glass slide and prepared
for the cytological and histopathological examination. Results. Out of 58
patients submitted to TBNA of mediastinal or hilar lymph nodes, adequate
material for cytological diagnostics was obtained in 53 (91.37%). Out of 53
adequate cytological samples, in 38 (71.69%) noncaseous granulomatous
inflammation (NGI) was found, while in corresponding histopathological
samples, NGI was found in 48 (90.56%), which was significantly higher (p <
0.05). Of cytological smears, out of the cell types typical for granulomatous
inflammation, in 26 (63.15%) patients the clusters of the epitheloid cells
were found, in 8 (21.05%) there were both, clusters of epitheloid cells and
giant multinuclear hystiocytes, and in 6 (15.76%) only single scattered
epitheloid cells or small clusters of several epitheloid cells were found.
The sensitivity of TBNA cytology in our group of patients with sarcoidosis
was 76%, specificity 100% and accuracy 77.34%. Conclusion. TBNA is an
efficient and safe procedure in the diagnosis of sarcoidosis, minimally
invasive and with a little risk of complications. Using 19 G needle enables
obtaining material for histological and cytological analyses, as well which
contribute to the sensitivity of diagnosting sarcoidosis. The value of this
type of diagnostics depends on qualification and experience both of
bronchoscopist and cytologist/pathologist, as well, of the interpreter of
such a material. |
