File:Cytopathology of pleomorphic adenoma.png| | File:Cytopathology of pleomorphic adenoma.png|'''Pleomorphic adenoma''' (Pap stain). It can usually be diagnosed by its typical fibrillary stroma (mesenchyme). Stromal cell nuclei are small. Myoepithelial cells are usually the predominant cell type, and can have various shapes but are usually more elongated than epithelial cells. Epithelial cells may have prominent nucleoli.<ref>Image by Mikael Häggström, MD.
