case_images: FIG2
case_images: Microscopically, the neoplasm was composed of mucin-secreting basaloid cells (Figure 2A). Immunohistochemical analysis showed positivity for p63, p40, CK7, GATA3, and CD56 and focal positivity for chromogranin while being negative for CD117, BerEP4, ER, PR, and synaptophysin (Figure 2B).
