major salivary gland tumors are uncommon and the exact nature of these tumors is not obvious. this study was carried out to compare the histological results of intraoperative frozen sections against those of permanent reports for major salivary glands masses. one hundred thirty-nine patients with major salivary gland masses who were candidates for surgery underwent an intraoperative frozen sect...

acinic cell carcinoma arising in salivary glands is a rare tumor, accounting for 2% to 5% of the primary neoplasms of the parotid gland. when these tumors are well-differentiated, the neoplasia has innocuous aspect, due to the similarity to normal parotid tissue. this makes the diagnosis difficult. initially the malignancy of this tumor was uncertain; however, recent studies have declared it as...

Salivary duct lithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions or sialoliths resulting in salivary ectasia and even provoking the subsequent dilation of the salivary gland. Sialolithiasis accounts for 30% of salivary diseases and most commonly involves the submaxillary gland (83 to 94%) and less fr...

background and aims. various morphologies are seen in different salivary gland tumorsor within an individual tumor, and the lesions show divers biological behaviors. experimental results support the hypothesis that increased crkii proto-oncogene is associated with cytokine-induced tumor initiation and progression by altering cell motility signaling pathway. the aim of this study was to assess t...

Introduction: Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors. Materials and Methods: In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with m...

Background and objective: Fine needle aspiration cytology (FNAC) of salivary gland lesions is an accepted and useful diagnostic tool to differentiate between benign and malignant lesions. Majority of the neoplasms are benign, and specific diagnosis on cytology can be made in most of the cases. However, the utility is limited by the overlapping and heterogeneous morphol...

conclusions the agnor technique can be used to diagnose salivary gland tumors. results the chi-square test showed significant differences between tumor types and the numbers of agnors (p = 0.000) and between tumor types and areas of agnors (p = 0.000). objectives the purpose of this study was to determine the numbers and mean areas of the agnor dots in the 3 most common salivary gland tumors. m...

Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...

background and aims. salivary gland tumors are rare and specific lesions. there are differences in the incidence and frequency of salivary tumors in both minor and major salivary glands in different countries. this study was carried out to determine the prevalence of major and minor salivary gland tumors in ahvaz in the south of iran. materials and methods. all the cases, recorded in imam khome...
