Pathology

FNA mass in right submandibular gland.

The FNA smears show classic features of pleomorphic adenoma:

  • cellular, with single to irregular groups and sheets of epithelial cells
  • interspersed stromal fragments
  • background population of myoepithelial cells - often described as having a 'plasmacytoid' appearance

FNA submandibular gland (pap stain) - The smears show large numbers of epithelial cells interspersed with vaguely fibrillary to whispy stroma.
