Aim The aim of this study was to investigate the correlation of preoperative presumptive and final histological diagnosis in patients without previous histological evaluation. Matherial and Methods We enrolled sixty-five patients who were operated for lung and mediastinal lesions between December 2005 and December 2008. In all patients, three presumptive diagnosises were established and they were compared to final histological diagnosis. ROC curve was used for analysing data. Results Postoperative histological diagnosis were as follows: lung cancer 23.1% (15/65), hydatid cyst 23.1% (15/65), sarcoidosis 13.8% (9/65), tuberculosis 9.2% (6/65) and other disease 30.8% (20/65). Sensitivity of presumption in the diagnosis of lung cancer, hydatid cyst, tuberculosis and sarcoidosis were 80%, 93.3%, 50%, 66.7% respectively. Conclusion We think that the exploratory thoracotomy should be performed when the lung cancer and hydatid cyst are suspected for diagnosis. For accurate diagnosis of tuberculosis and sarcoidosis, more detailed and careful preoperative laboratory studies should be done.
