Overview

The pathophysiology of salivary gland tumors depends on the histological subtype.

Pathophysiology
Entity Architecture Morphology Cell borders Cytoplasm Nucleus Differential Diagnosis Other
Pleomorphic adenoma Variable mixed proportion; must include:
  • myoepithelium
  • mesenchymal stroma
  • epithelium (ductal cells) or
  • chondromyxoid stroma
 Variable Variable Plasmacytoid Adenoid cystic carcinoma Occasionally encapsulated, mixed proportion of glandular, myoepithelial and mesenchymal cells
Warthin tumor Papillary, bilayer Cuboid (basal), columnar (apical) Clearly seen Eosinophilic, abundant Unremarkable Sebaceous lymphadenoma AKA papillary cystadenoma lymphomatosum
Basal cell adenoma variable, islands surrounded by hyaline bands, lesion encapsulated Basaloid Subtle Scant, hyperchromatic Granular Basal cell adenocarcinoma
Canalicular adenoma Chains of cells Cuboid or columnar Subtle Scant, hyperchromatic Granular Basal cell adenoma Exclusively oral cavity, 80% in upper lip; immunohistochemistry: p63-
Sialoblastoma variable, islands surrounded by loose fibrous stroma Basaloid Subtle Scant, hyperchromatic Granular Adenoid cystic carcinoma Basal cell adenocarcinoma
