INTRODUCTION: Pericardial effusion (PE) is a common clinical condition that can develop as a result of systemic or heart disease. In our study, we synthesized the cytopathological and clinical results of patients who underwent pericardiocentesis due to pericardial effusion. METHODS: 213 patients who underwent percutaneous pericardiocentesis between 2007-2017 were included in the study: cytologic and histopathologic diagnoses were noted and their relations were examined. RESULTS: 132 cases were male (61.9%), 81 were female (38.1%) and the mean age was 59.9 (min 13 - max 97). According to cytologic findings; 168 had benign cytology (78.9%), 10 had suspicious cytology (4.6%), 3 had non-diagnostic (1.4%) and 32 had malignant cytology (15.1%). Benign pericardial effusion is the most common diagnosis. Malignant cytology findings were interpreted as 20 (62,5%) lung carcinoma, 1 (3.1%) rhabdomyosarcoma, 2 (6.2%) poorly differentiated adenocarcinoma, 4 (12.5%) gastrointestinal system related carcinoma, 1 (3.1%) undifferentiated epithelial tumor, 1 (3.1%) breast carcinoma, and 3 (9%) malignant tumor which were not specified. Four (2.4%) of the 168 patients diagnosed with benign cytology were diagnosed with malignancy previously and there was no malignancy finding in the cytological specimen. Three (30%) of the 10 patients with suspicious cytology, had malignancy diagnosis previously. DISCUSSION AND CONCLUSION: In developed countries, it is reported that more than 50% of the PE's are idiopathic. The percentage of cancer-associated PE's is 10-25%. In our study, 78.9% were benign and 15.1% were malignant PE consistent with the literature. Cytological sampling in pericardial fluid is a method that can shed light on the diagnosis of many diseases.
