The patient went on to have a FNAC.
Cytology
Multiple smears prepared from the FNA of the right parotid gland show ductal epithelial and myoepithelial cells situated in a fibromyxoid stroma. Some of the cells show plasmacytoid pattern. The appearances are those of a pleomorphic adenoma.
Discussion
Pleomorphic adenomas account for 70-80% of benign salivary gland tumors and are especially common in the parotid gland, and are most often located in the superficial lobe.
Three histological types have been described:
- myxoid (hypocellular) - which is the most frequently observed.
- cellular
- classic
The myxoid type has a very hyperintense appearances as in this case.
