Cytological study of salivary glands

  • How do you investigate salivary glands?

    Your doctor will feel your jaw, neck and throat for lumps or swelling.
    Imaging tests.
    Imaging tests, such as magnetic resonance imaging (MRI), computerized tomography (CT), positron emission tomography (PET), ultrasound or X-ray, may help your doctor determine the size and location of your salivary gland tumor..

  • How do you test salivary glands?

    Salivary gland function is assessed by the pattern of uptake and secretion of a radioactive tracer, technetium 99.
    Salivary gland scans can help evaluate patients with persistent symptoms of a dry mouth.
    They are also utilized to evaluate salivary gland swelling due to either infection, inflammation, or obstruction..

  • What is a salivary gland specialist called?

    More commonly known as ear, nose and throat physicians (ENTs), Northwestern Medicine otolaryngologists specialize in the diagnosis, treatment and rehabilitation of diseases and disorders of the head and neck, including salivary gland disease..

  • What is the diagnostic imaging of the salivary glands?

    CT scanning and MRI
    Computed tomography (CT) scanning or magnetic resonance imaging (MRI) is useful for determining the extent of large tumors, for evaluating extraglandular extension, for determining the actual depth of parotid tumors, and for discovering other tumors in one gland or in the contralateral gland..

  • An X-ray, CT scan or MRI to look for stones or tumors.
    A fine needle biopsy to determine if a tumor is cancerous.
    Salivary function tests, eye tests and blood tests to diagnose Sj\xf6gren's syndrome.
    A sialogram X-ray that uses dye to look for problems in the salivary ducts.
  • In salivary gland masses, FNAC serves to determine the nature of the lesion (inflammatory/neoplastic – benign or malignant) and in some cases, the specific diagnosis.
  • The major salivary glands are best examined by palpation and by observation of the salivary effluent during palpation.
    Only the parotid gland and the submandibular glands can be examined in this way.
Fine-needle aspiration cytology (FNAC) is the first tissue-based procedure applied before any surgical intervention. It has now been widely accepted by head and neck surgeons as an excellent though challenging, the primary method of evaluating the space occupying lesions of salivary gland.
The normal cytological characteristics of salivary gland tissue are studied from the unintentional aspiration of normal tissue while aspirating abnormal tissue. FNAs of the normal salivary gland aspirate shows glandular (i.e., acinic cells), ductal elements, adipose tissue and scattered inflammatory cells.

What is salivary gland aspiration cytology (FNAC)?

Salivary gland lesions constitute 2%–6% of all head-and-neck tumors. [ 1] Fine-needle aspiration cytology (FNAC) is a useful tool for evaluating suspicious salivary gland lesions because it is simple, cost-effective, reliable and minimally invasive with a high specificity and sensitivity.

What is the classification of salivary gland cytopathology?

The cases were retrieved from register of cytology division and analyzed according to Milan System of classification of salivary gland cytopathology into following diagnostic categories:

  1. nondiagnostic
  2. nonneoplastic
  3. atypia
  4. benign
  5. neoplasm of uncertain malignant potential (NUMP)
  6. suspicious for malignancy
  7. malignant

What is the role of Fine-needle aspiration in the diagnosis of salivary gland lesions?

The role fine-needle aspiration (FNA) in the diagnosis of salivary gland lesions has evolved over the years.
Although clinical and radiological parameters help to narrow the differential diagnosis the tissue diagnosis still remains the gold standard.

Medical condition

Sarcomatoid carcinoma of the lung is a term that encompasses five distinct histological subtypes of lung cancer, including (1) pleomorphic carcinoma, (2) spindle cell carcinoma, (3) giant cell carcinoma, (4) carcinosarcoma, or (5) pulmonary blastoma.
