Schematic showing the major salivary glands. (WC)

The salivary glands help digest food. ENT surgeons excise them if a malignancy is suspected.

The cytopathology of the salivary glands is covered in the Head and neck cytopathology article.

Normal salivary glands

Types of salivary glands

Types of glands:[1]

  1. Serrous - eosinophilic cytoplasmic granules, acinar arrangement - vaguely resembles the acinar morphology of the pancreas.
  2. Mucinous - light eosinophilic staining.

Identifying the glands

The three main glands:

  1. Parotid:
    • Serous glands - lower viscosity, acini (lobules).[2]
    • Most tumours in this gland are benign.
  2. Submandibular:
    • Serous and mucinous glands.
      • Serous ~90% of gland.
      • Mucinous ~10% of gland.
    • Serous demilunes = mucinous gland with "cap" consisting of a serous glandular component.
  1. Sublingual:
    • Mucinous glands.

Other:

  • Adipose tissue is found between the glands.
    • It increases with age.

Images:

Memory devices:

  • The parotid gland vaguely resembles the pancreas.
  • Submandibular = glands are mixed.

Palate

Benign parotid tumours

Oncocytic tumours

Clear cell tumours

Basaloid neoplasms

IHC overview

General:

  • Usually has limited value.

Overview:

  • Luminal markers: CK7, CK19, CAM5.2 (LMWK).
  • Basal markers: p63, HMWK, CK14.
  • Myoepithelial markers: calponin, actin.
  • Uncommitted: S-100.

Notes:

  • p63 and S-100 are sometimes call myoepithelial.

Specifics:

  • Calponin, S-100, Ki-67 may be useful as per Nagao et al.[8]

Benign

General DDx:

  • Inflammation.
  • Neoplasm.
  • Ductal obstrution.

Chronic sialadenitis

Salivary gland mucocele

General

  • Benign.
  • Infected mucocele = mucopyocele.

Microscopic

Features:[9]

  • Granulation tissue-like and pseudocyst-like.
    • Granulation tissue-like:
      • Fibroblasts.
      • Small caliber blood vessels.
      • Histocytes.
      • Neutrophils.
    • Pseudocyst:
      • No epithelial lining.
      • Poorly circumscribed.
  • Pale pink extracellular material (mucous) - key feature.
  • +/-Granulomas.[10]

LESION, LEFT LOWER LIP, EXCISION:
- BENIGN MUCOCELE.

Micro

The sections show a stratified squamous epithelium with a thin layer of parakeratosis, minor salivary glands, and a well-circumscribed cystic lesion.

The cystic lesion has a mildly fibrotic appearing wall, is lined by histiocytes intermixed with rare lymphocytes, and contains mucous and macrophages. No significant nuclear atypia is identified. Mitotic activity is not readily apparent.

Pleomorphic adenoma

Myoepithelioma

Basal cell adenoma

General

  • ~2% of salivary gland tumours.
  • May be multifocal.
  • Usually parotid gland, occasionally submandibular gland.
  • Female:male = ~2:1.
  • May be seen in association with dermal cylindromas in the context of a genetic mutation.[11]
  • Malignant transformation - rarely.

Microscopic

Features:

  1. Basal component.
    • Basophilic cells - key feature.
    • Usu. in nests.
    • Large basophilic nucleus.
    • Minimal-to-moderate eosinophilic cytoplasm.
  2. Stromal cells.
    • Plump spindle cells without significant nuclear atypia - distinguishing feature.
      • Stromal cell nuclei width ~= diameter RBC.
    • Dense hyaline stroma.
  3. Tubular component.
    • Within basal component, may be minimal.
  4. Lesion is encapsulated - key feature.

Notes:

  • No chondromyxoid stroma.
  • Neoplastic cells embedded in stroma ("stromal invasion") = basal cell adenocarcinoma.
    • Basal cell adenocarcinoma may be cytologically indistinguishable from basal cell adenoma, i.e. "bad" architecture makes it a basal cell adenocarcinoma.

Canalicular adenoma

Warthin tumour

Sebaceous adenoma

Sebaceous lymphadenoma

Oncocytoma of the salivary gland

  • AKA salivary gland oncocytoma.

Malignant

One approach:

  • Differentiate -- luminal vs. myoepithelial vs. basal (mucoepideroid).

Mucoepidermoid carcinoma

Acinic cell carcinoma

Adenoid cystic carcinoma

Note: The breast tumour is dealt with in adenoid cystic carcinoma of the breast.

Salivary duct carcinoma

Intraductal carcinoma of the salivary gland

Polymorphous low-grade adenocarcinoma

  • Abbreviated PLGA.

Carcinoma ex pleomorphic adenoma

  • Abbreviated Ca ex PA.

Epithelial-myoepithelial carcinoma

Basal cell adenocarcinoma

Sebaceous carcinoma

It is similar to the tumour found in the skin.
