OROPHARYNGEAL MUCOEPIDERMOID CARCINOMA Figure 2-37 OROPHARYNGEAL MUCOEPIDERMOID CARCINOMA Typical mucoepidermoid carcinoma with a mixture of cystically dilated luminal spaces with mucinous material, solid collections of epidermoid cells with round nuclei and eosinophilic cytoplasm, and mixed More about this image found in OROPHARYNGEAL MUCOEPIDERMOID CARCINOMA Typical mucoepidermoid carcinoma wi...

LOW-GRADE NONINTESTINAL SINONASAL ADENOCARCINOMA Figure 1-53 LOW-GRADE NONINTESTINAL SINONASAL ADENOCARCINOMA A–C: Many cases show serous differentiation in the form of expression with S-100 protein (A), SOX10 (B), and DOG1 (C). D: Mucinous areas are negative for these markers, as demonstrated More about this image found in LOW-GRADE NONINTESTINAL SINONASAL ADENOCARCINOMA A–C: Many cases show sero...

surrounded by smaller cysts and extravasated mucin. C: Multicystic low-grade MEC. D: Intermediate-grade MEC is composed of an admixture of mucous, intermediate, and epidermoid cells. More about this image found in MUCOEPIDERMOID CARCINOMA (MEC) A: Hemimaxillectomy for MEC arising in the ...

subtype of adenoid cystic carcinoma often presents in the nasopharynx at an advanced stage. B: Intermediate-grade mucoepidermoid carcinoma shows a combination of epidermoid, intermediate, and rare goblet-type mucinous epithelial cells.

: Tumor cells infiltrate the native mucous glands and should not be interpreted as mucinous differentiation. D: Targetoid perineural invasion is a common finding in which the tumor cells create a whorled appearance around the nerve (black arrows). A slate blue-gray stroma is a characteristic finding.
