Comparison of preoperative and postoperative pathology report results:
It was determined that in some cases even though the preoperative pathology result was conventional SCC, the final result was a vSCC. We have determined that 66%, 100%, 53.3% and 38.5% of the preoperative pathology reports were conventional SCC in patients with adenosquamous, acantholytic, basaloid and spindle cell carcinoma, respectively (Figure 1 ). For other variants (lymphoepithelial, papillary and verrucous carcinoma), a difference between primary and final pathology reports was not observed. Furthermore, no pathological subgroup changes after surgical treatement were observed in any patient diagnosed with primary vSCC.
