Histopathologic examination showed multiple tumor islands and strands eomposed of basaloids cells embedded in a moderately cellular fibroblastic stroma and the for vation of bud-like extension of tumor cell nest. The peripherel basaloid cells shovred a palisading arrangement and small keratinous cysts were formed in tumor islands.
