  • 20 ][ Level of evidence: 3iiiDii ] Unresectable or recurrent tumors may respond to chemotherapy. (uni-bonn.de)
  • The most common subtype of malignant PA is CXPA which develops in primary or recurrent PA. (semanticscholar.org)
  • It is also helpful to consider the presenting symptoms in terms of either single or multi-gland involvement, and the type of swelling present (recurrent swelling, diffuse swelling or a well-defined lump - see table 1), as this information helps differentiation between the five diagnostic categories of disease.

  • 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)
  • Conclusion: Magnetic resonance imaging especially done at higher tesla systems like 1.5T & 3T with the use of contrast and advanced sequences is highly useful in the evaluation of spinal tumors not only for diagnosis but for surgical planning also. (ijrhs.org)
  • What is the most likely diagnosis for the most aggressive type of this tumor? (brainscape.com)
  • 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)
  • 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)
  • However, in addition to squamous epithelium, there is also lymphoid tissue and minor salivary glands, so that lymphoma and salivary gland tumors can also arise in this area 1 . (ucsd.edu)
  • Eventual periductal and interlobular (inside the gland) sclerosis (replacement of regular tissue with hard connective tissue). (wikipedia.org)
  • Salivary gland-like carcinomas of the lung generally refers a class of rare cancers that arise from the uncontrolled cell division (mitosis) of mutated cancer stem cells in lung 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)
  • parapharyngeal
  • 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)
  • It is often this plane that is most helpful in evaluating tumor spread along important fascial spaces that are vertically oriented, such as the carotid space, the parapharyngeal space, the retropharyngeal space, and the prevertebral space. (ucsd.edu)
  • Contemporary evaluation and management of parapharyngeal space neoplasms. (medindia.net)
  • Clinical
  • Materials & Methods: Forty- nine patients who were admitted in the Dept. of Neurosurgery with clinical suspicion of spinal tumor were evaluated on a GE Medical System, Sigma 1.5 T, Sys # GEMSOW scanner. (ijrhs.org)
  • 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.

  • ducts
  • Abnormalities of the salivary gland ducts leading to excessive accumulation or retention of ductal secretions, which can excite chronic inflammations. (wikipedia.org)
