OBJECTIVE: Cytological examination of pleural fluids is a fast, efficient and non-invasive diagnostic method. Identification of malignant effusions bears critical importance in treatment and prognosis. The aim of this study was to investigate the distribution of cytopathologic diagnoses in @entity1143 and the cyto-histopathologic correlation rates. MATERIAL AND METHOD: A total of 298 pleural fluid cases diagnosed from 2008 to 2009 in our laboratory were retrospectively identified as the study group. Evaluation results were classified in 5 groups as inconclusive, benign, atypical, suspicious and malignant, and compared with the biopsy results. RESULTS: Of the total 298 pleural fluid cases, 114 (38.3%) were females and 184 (61.7%) were males. The age range was between 15 and 89 with a mean value of 58.4 +/- 17.8. Of the cases, 3 (1%) were diagnosed as inadequate, 246 (82.6%) benign, 8 atypical, 10 suspicious, and 31 malignant by cytology. Among the cases who were diagnosed as malignant, 24 (8.1%) were reported as @entity189 and 7 (2.3%) as @entity3620 . Of the 8 cases reported as atypical, biopsy results of 2 showed @entity3620 , and of the 10 cases reported as suspicious, 1 case whose biopsy result was obtained was diagnosed as @entity957 metastasis. CONCLUSION: Cytological examination is the most valuable diagnostic method for @entity1143 which may have various etiological causes. The most common cause of @entity1143 in our region is metastatic @entity189 including those from the lung, @entity5344 , followed by @entity3620 .
