PLAG1 and mixed neoplasm: In the etiopathogenesis of pleomorphic adenoma, it is proposed that genetic alterations or aberrant signalling pathways such as PLAG1 [13, 14] lead to uncontrolled proliferation and abnormal differentiation of myoepithelial cells, resulting in the formation of the characteristic mixed tumour composed of epithelial and myoepithelial components as discussed by various authors [10, 14, 15].
