Abstract: Our experience with cytological examinations of tumorous mediastinal lesions is evaluated. A group of 117 patients with mediastinal tumor have been included into the study. Among them carcinomas prevailed (60,7%), followed by lymphomas (18,8%), other tumors (15.4%) and thymic neoplasms (5.1%). Malignantor suspicious cells were found in 77.4% of patients with carcinoma. The cells indicating a possibility of non-Hodgkin's lymphoma were found in 9 out of 14 patients. In 5 out of 6 thymic neoplasms the cytological pattern wasconsistent with the diagnosis of thymic neoplasm. One case of thymoma was cytologically falsely diagnosed as malignant lymphoma. One case of neurofibroma was falsely diagnosed as adenocarcinoma. The sensitivity of cytological examinations was 67.5%. If 18 patients with diagnostically unsatisfactory material were excluded from the analysis, the sensitivity wouldincrease to 80.8%. Owing to the wide variety of primary and metastatic tumors that can occur in the mediastinum, apart from the routine cytological techniques, additional staining methods should be used. For final cytological diagnosis the integration of cytological findings with clinical and radiological data is often required. Owing to the characteristics of the obtained material and biological behaviour of some mediastinal tumors, some tumors cannot be definitively diagnosed by cytological examinations alone.
