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.
