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.
