Head and Neck Imaging

Adenocarcinoma, head and neck

malignant neoplasm of epithelial cells in glandular or glandlike pattern. Adenocarcinomas are those glandular malignancies that cannot be placed within another more definable class of tumour, such as acinic cell carcinoma, mucoepidermoid carcinoma or adenoid cystic carcinoma. They have a pronounced predilection for the ethmoid sinuses and the superior part of the nasal cavity (see sinonasal cavities cancer). About 15% of the malignant tumours in the parotid gland correspond to adenocarcinoma. It is rarely seen in other head and neck sites.
