    Salivary glands


    Parotid and submandibular glands may be resected after fine needle aspiration (FNA) investigation due to the presence of a benign tumour, such as a pleomorphic adenoma or Warthin’s tumour.

    Malignant neoplasms are rare but primary salivary gland tumours such as mucoepidermoid, acinic cell, adenoid cystic, squamous cell and salivary duct carcinomas do occur.1-8

    The resection procedure may be a superficial parotidectomy (superficial lobe not including the facial nerve), total parotidectomy (superficial and deep lobes, including the facial nerve) or a submandibulectomy (total excision of the submandibular gland). Radical neck dissections may be required for treatment of head and neck malignancies.6 See the neck dissection protocol for more detail.

    Record the patient identifying information and any clinical information supplied together with the specimen description as designated on the container. See overview page for more detail on identification principles.

    • No
      • Non-routine fixation (not formalin), describe.
    • Yes

      • Ensure samples are taken prior to fixation.
    • Not performed
    • Performed, describe type and result
      • Frozen section

    See general information for more detail on specimen handling procedures.

    Inspect the specimen and dictate a macroscopic description.

    External Inspection

    Orientate and identify the anatomical features of the specimen.

    If possible, complex specimens should be examined and orientated together with the responsible surgeon. Alternatively, the surgeon should orientate the specimen with the use of designated sutures or pin the specimen out on an appropriately labelled cork board.2

    Record additional orientation or designation provided by operating clinician:

    • Absent
    • Present
      • Method of designation (e.g. suture, incision)
      • Featured denoted

    Photograph the intact specimen if required.

    Describe the following features of the specimen:

    Specimen integrity

    • Intact
    • Fragmented, describe

    Specimen laterality

    • Left
    • Right
    • Unoriented


    Record as stated by the clinician.1

    • Incisional biopsy
    • Excisional biopsy of minor gland
    • Resection of submandibular gland
    • Extended resection of submandibular gland (surgeon to indicate extent of anatomical resection)
    • Resection of sublingual gland
    • Superficial parotidectomy +/- facial nerve sacrifice
    • Total parotidectomy
      • Facial nerve preservation
      • Facial nerve sacrifice
      • Extended radical total parotidectomy (includes resection of parotid gland, facial nerve, masseter muscle, zygoma and mandible)
    • Other, describe

    Anatomical components included (more than one may apply) & dimensions (mm)

    • Total specimen, in three dimensions1,2,6

    If multiple fragments are received, the collective size of all tissue is measured in three dimensions2

    Describe and measure the anatomical components present.

    • Minor salivary gland
    • Parotid
    • Submandibular gland
    • Sublingual gland
    • Skin, note any skin lesions and refer to the skin protocol for more information.
    • Other, describe


    Minor salivary glands may be small specimens <15mm in maximum dimension. Bisect the gland transversely.

    Resection specimens may or may not be orientated by the clinician. If the specimen is orientated, paint the designated margins with an appropriate number of coloured inks allowing recognition of all the denoted margins and/or structures and record the colours applied.

    Section the specimen at sequential intervals to best demonstrate the relationship of the lesion to the margins.2 This is usually along the transverse axis.

    After opening the specimen may require longer fixation in larger quantity of formalin.

    Internal Inspection

    Describe the internal or cut surface appearance including the following items:1,6


    • Absent
    • Present
      • Number; if more than one tumour, designate and describe each tumour separately

    Tumour size (mm)1

    • In three dimensions

    Tumour size is an important prognostic factor for treatment outcome and survival.1,5-8

    Tumour site1

    • Describe if relevant, or record with an annotated photograph.

    Tumour appearance1,2,6

    • Solid
    • Cystic
    • Gelatinous

    Distance of tumour to margins (mm)

    • Distance of tumour to the surgical resection margins
    • Specify each margin

    Macroscopic extraparenchymal extension1

    • No
    • Yes, specify tissues involved
      • Surrounding fat
      • Skeletal muscle
      • Skin
      • Nerve
      • Other, specify

    Other abnormalities present

    • Cysts
    • Stones
    • Other, describe

    Retrieved from resection specimen

    • Describe site(s)
    • Number retrieved

    Separately submitted

    • For each specimen container, record specimen number and designation
    • Collective size of tissue in three dimensions (mm)
    • Number of grossly identified lymph nodes submitted
    • Maximum diameter of each (mm)

    Sentinel, left and right neck dissection1

    • Level
      • Submental (IA)
      • Submandibular (IB)
      • Upper jugular (IIA and IIB)
      • Middle jugular (III)
      • Lower jugular (IV)
      • Posterior triangle (VA and VB)
      • Anterior triangle (VI)

    See neck dissection protocol for more detail.

    Photograph the dissected specimen if required.

    Note photographs taken, diagrams recorded & markings used for identification.


    Dissect the specimen further & submit sections for processing according to the diagram provided.

    Submit representative sections of:1,6

    • Surgical resection margins
    • Tumour or lesion
      • If <30 mm, it may be appropriate to submit all the tumour
      • If >30 mm, at least one section per 10 mm of tumour
    • All macroscopically different areas particularly at the edge of the tumour
    • Tumour interface with non-lesional/extraparenchymal tissue
    • Relationship of tumour to close (eg <10 mm) surgical margin(s)
    • Surgical resection margins of any large nerves included

    Submit all lymph nodes & identify the site of each.

    Record details of each cassette.

    An illustrated block key similar to the one provided may be useful.
