Few salivary lesions

Adenoid cystic carcinoma

'cribriform'

A nicer looking version



Acinic cell carcinoma

Cytology







Granular cytoplasm

Polymorphic adenoma

Looking like fibroadenoma, with plasmacytoid myoepithelial cells






More plasmacytoid cells








Stromal fragment
Pleomorphic adenoma on cytology

Epithelial myoepithelial carcinoma

Note the clear cells around acini

Warthin tumor

Note the double layered oncocytic epithelium


Basal cell adenoma




Mucoepidermoid cancer in a teenage girl



Mixed tumor on cytology

Note bright red to purple stromal fragments




Polymorphic adenoma, ? canalicular adenoma










Column chromatography
