In benign and malignant myoepithelial tumors, VIM labeling in all cases, loss of all other suprabasal myoepithelial markers, and the scant positivity to CK14 in spindle cells were indicative of a prevailing expression of the myoepithelium motile state and a possible passage from simple myoepithelial cells to mesenchymal fibroblasts. The gene discussed is KRT14; the disease is myoepithelial tumor.
