abnormal parotid gland myoepithelium morphology 
any structural anomaly of the stellate-shaped contractile cells with long dendritic processes that surround the secretory acini and intercalated ducts of the parotid gland, usually found in the glandular epithelium as a thin layer above the basement membrane but generally beneath the luminal cells; they display features of both smooth muscle and epithelium, such as numerous microfilaments with focal densities in the cytoplasmic processes, and desmosomes which attach them to the epithelial cells; their functions include contraction when the gland is stimulated to secrete, compressing or reinforcing the underlying parenchymal cells, thus aiding in the expulsion of saliva and preventing damage to the other cells

absent parotid gland  
decreased parotid gland size
