Patient Data

There is a sharply marginated, oval mass involving the tail of the right parotid gland, it elicits a low signal intensity on T1-weighted images and very high signal intensity on T2-weighted images with intense post-contrast enhancement. The mass measures 2 x1.7 x 1.6 in its CC, AP and TS diameters. 

Case Discussion


Cellular smears show an abundance of fibromyxoid fibrillery matrix material with spindle cells and plenty of plasmacytoid epithelial cells in the background. Overall, the appearances favor a cellular pleomorphic adenoma, myoepithelial rich.
