Aim: Salivary gland tumours are rare head and neck neoplasms that histologically make up a very heterogeneous tumour group. The most important diagnostic method is an ultrasound exam of the salivary gland with cytopunction of a tumour. The aim of the paper is to determine the specificity and sensitivity of the cytological findings and to determine the degree of agreement between the cytological and histopathological findings. Patients and methods: This study encompassed 49 patients who underwent surgery due to salivary gland tumors between 2015-2017. Only patients with preoperative cytologic findings and postoperative histopathological findings were compared. Results: The most frequent group of patients were those over 60 years (57%). The salivary gland was the most common cancer site in 94% of patients. According to the cytological finding, 40 benign and 9 malignant tumours were diagnosed. In the histopathological study of lesions, 39 were diagnosed as benign and 10 as malignant. The most common histopathological diagnosis was Warthin's tumor (cystenolymphoma) in 52.5% and pleomorphic adenom in 37.5% of patients. Based on the data, sensitivity was 90% and specificity was 100%. Kappa statistics for the degree of agreement between fine needle aspiration cytology and histological results were 0.93 (95% CI = 0.687-0.979). Conclusion: In our study, FNAC proved to be a very good method in the diagnosis of salivary gland tumours with high sensitivity and specificity, and excellent degree of agreement between FNAC and final diagnosis.

Objectives: Computerized tomography (CT) is the most accurate method for evaluating pelvic calcifications, which are of utmost importance for planning kidney transplantation (KT). The aim of our study was to evaluate the incidence and distribution of iliac artery calcifications and correlate the novel pelvic calcification score (PCS) with cardiovascular risk factors and graft and overall survival in KT patients. Methods: We retrospectively included 118 KT patients operated at our institution with pretransplant pelvic CT. Calcification morphology, circumference and length of both common and external iliac arteries were independently scored by two uroradiologists. PCS was calculated as the total score sum of all three calcification features in all vessels. PCS correlation with graft and patient survival was performed. Results: Calcification in at least one vascular segment was found in 79% of patients. PCS was significantly higher in male patients (p = 0.006), patients over 55 years (p < 0.001), and patients on haemodialysis (p = 0.016). Patients with a PCS >3 had significantly shorter graft and overall survival rates (p = 0.041 and p = 0.039, respectively). Conclusions: The extent of iliac artery calcification in KT recipients quantified by PCS on pretransplant CT correlates with graft and overall patient survival. A PCS over three was associated with worse clinical outcomes and could become a possible prognostic factor. Advances in knowledge: Our novel PCS is a robust method for quantifying iliac artery calcification burden. Since higher a PCS correlates with worse patient and graft survival, PCS has the potential to become a prognostic factor in kidney transplant patients. [ABSTRACT FROM AUTHOR]
