Definition / general
  • Classification difficult because most tumors arise from or differentiate to epithelial or myoepithelial cells, which can undergo various metaplastic changes (oncocytic, chondroid, squamous, sebaceous)
  • Subtypes are clustered based on expression of myoepithelial, luminal and basal cell phenotypes (Mod Pathol 2004;17:803)
  • WHO classification: stresses distinction between benign and malignant
