  • pathology
  • Objective: Salivary gland tumours constitute an important aspect of oral and maxillofacial pathology. (thefreelibrary.com)
  • Materials and Methods: This was a 4 year descriptive cross - sectional study (from 1st July 2008 - 30th June 2012) on 259 salivary gland tumours reported at the Department of Pathology, King Edward Medical University, Lahore. (thefreelibrary.com)
  • 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)
  • 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)
  • 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)
  • 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)
  • 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)
  • classification
  • 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. (wikipedia.org)
  • ductal
  • Be alert to the potential for a breast ductal cancer to metastasize to the parotid region. (renalandurologynews.com)
  • Tumor cells can be tested by immunohistochemistry which shows: Ductal cells: positive with keratins, CK7 and CK19. (wikipedia.org)
  • Abnormalities of the salivary gland ducts leading to excessive accumulation or retention of ductal secretions, which can excite chronic inflammations. (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
  • 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)
