• diagnosis
  • Successful diagnosis and treatment of patients with salivary gland tumors require a thorough understanding of tumor etiology, biologic behavior of each tumor type, and salivary gland anatomy. (medscape.com)
  • What is the most likely diagnosis for the most aggressive type of this tumor? (brainscape.com)
  • Diagnosis of metastatic disease for patients affected by submandibular swelling with a previous history of RCC should be always considered. (omicsonline.org)
  • 4) A panel of markers, such as vimentin and cytokeratin (especially k5 and k14), may be used for immunohistochemical diagnosis of these tumors in mice. (askjpc.org)
  • It is only upon post-surgical histopathology of the excised mass that the diagnosis of Küttner's tumor is definitively made. (wikipedia.org)
  • Given the difficulties of a definitive pre-operative diagnosis, the clinical entity of Küttner's tumor has so far remained significantly under-reported and under-recognized. (wikipedia.org)
  • In recent times, armed with a better understanding of the occurrences and observable features of this condition, surgeons are increasingly depending upon pre-operative ultrasonography along with Fine-needle aspiration cytological (FNAC) examinations to make an accurate presumptive diagnosis, and according to one estimate, about 44% of patients undergoing submandibular resection are found to have this condition. (wikipedia.org)
  • The diagnosis of salivary gland tumors utilize both tissue sampling and radiographic studies. (wikipedia.org)
  • characterize
  • The aim of our study was to characterize the clinical-radiologic-pathologic spectrum of parotid oncocytomas in a series of 10 cases seen in our institution between January 2003 and November 2008. (ajnr.org)
  • In terms of imaging studies, ultrasound can determine and characterize superficial parotid tumors. (wikipedia.org)
  • predominantly
  • This tumor predominantly consists of intraductal components and frequently exhibits papillary-cystic or cribriform proliferation pattern. (humpath.com)
  • tissue
  • Perhaps the most widely used currently is that system proposed by the World Health Organization in 2004, which classifies salivary neoplasms as primary or secondary, benign or malignant, and also by tissue of origin. (wikipedia.org)
  • Superior soft tissue contrast is possible with MRI leading to better definition between tumor and adjacent structures. (scribd.com)
  • Superior soft tissue contrast is possible with MRI leading to better delineation between tumor and adjacent musculature, especially in the tongue and floor of mouth where relatively little fat is present between tissue planes. (ucsd.edu)
  • Eventual periductal and interlobular (inside the gland) sclerosis (replacement of regular tissue with hard connective tissue). (wikipedia.org)
  • Although it is "benign" the tumor is aneuploid, it can recur after resection, it invades normal adjacent tissue and distant metastases have been reported after long (+10 years) time intervals. (wikipedia.org)
  • CT allows direct, bilateral visualization of the salivary gland tumor and provides information about overall dimension and tissue invasion. (wikipedia.org)
  • Most of these substances enter the salivary gland acinus and duct system from the surrounding capillaries via the intervening tissue fluid, although some substances are produced within the glands themselves. (wikipedia.org)
  • neoplastic
  • In humans, salivary gland myoepitheliomas are classified based on morphology (plasmacytoid, spindle, stellate, clear or epithelioid) of the neoplastic cells into spindle cell myoepithelioma, clear cell myoepithelioma, etc. (askjpc.org)
  • lymph nodes
  • Additionally, CT scanning and MRI are helpful in distinguishing an intraparotid deep-lobe tumor from a parapharyngeal space tumor and for evaluation of cervical lymph nodes for metastasis. (medscape.com)
  • Whether the tumor involves the facial nerve, has fixation to the skin or deep structures, or has spread to lymph nodes or distant sites. (healthlinkbc.ca)
  • Parotid gland because it is a large gland with lymph nodes embedded in it. (brainscape.com)
  • patients
  • 1 , 2 ] Most patients with malignant salivary gland tumors are in the sixth or seventh decade of life. (healthlinkbc.ca)
  • However, since different forms of malignant tumors generally exhibit diverse genetic, biological, and clinical properties - including response to treatment - accurate classification of lung cancer cases are critical to assuring that patients with lung cancer receive optimum management.
