Figure 2: (a) Cut surface at maximal diameter. Upper tumor was close to the submandibular gland (arrowhead). The area of curved line indicates MEC. (b–d) Hematoxylin and eosin (HE) staining (original magnifications: (b) ×40 (inset ×200), (c), (d) ×100). (b) Upper tumor showed cellular islands, in which tumor cells were squamoid while other showed mucin secretion. (c) The site of skin implantation was caused by MEC. (d) MEC and submandibular gland were separated by fibrous tissue.
