Results: Tumors expressing myoepithelial markers were ADC (SMA, Calponin), BCA (SMA, Calponin, p63), PA (SMA, Calponin, S100, CD10, GFAP, p63), ME (S100, CD10, GFAP), MEC (p63) and WT (p63); PA being the only tumor expressing all of the markers in the panel. GFAP, S100, CK14, p63, CK5/6 and Galec-tin3 expressions were higher in benign and CK19 was higher in malignant tumors (p < 0.05). Some of our findings helping in differential diagnosis are as follows:
