Lip, Oral Cavity and Oropharynx
ICD-O-3 topography code:	C00-C06, C09-C10, C14
ICD10:	C00-C06, C09-C10, C14

A malignant neoplasm which occurs typically in the major salivary glands (most frequently in the parotid gland), but also in the minor salivary glands of the oral mucosa and the tracheobronchial tree. It is characterized by the presence of ductal structures which are lined by an inner layer of cuboidal epithelial-type cells and an outer layer of myoepithelial cells with clear or eosinophilic cytoplasm.

Salivary glands
ICD-O-3 topography code:	C07-C08
ICD10:	C07-C08

A malignant neoplasm which occurs typically in the major salivary glands (most frequently in the parotid gland), but also in the minor salivary glands of the oral mucosa and the tracheobronchial tree. It is characterized by the presence of ductal structures which are lined by an inner layer of cuboidal epithelial-type cells and an outer layer of myoepithelial cells with clear or eosinophilic cytoplasm.

Nasal cavity and Sinuses
ICD-O-3 topography code:	C30-C31
ICD10:	C30-C31

A malignant neoplasm which occurs typically in the major salivary glands (most frequently in the parotid gland), but also in the minor salivary glands of the oral mucosa and the tracheobronchial tree. It is characterized by the presence of ductal structures which are lined by an inner layer of cuboidal epithelial-type cells and an outer layer of myoepithelial cells with clear or eosinophilic cytoplasm.

Bronchus and lung
ICD-O-3 topography code:	C34
ICD10:	C34

A malignant neoplasm which occurs typically in the major salivary glands (most frequently in the parotid gland), but also in the minor salivary glands of the oral mucosa and the tracheobronchial tree. It is characterized by the presence of ductal structures which are lined by an inner layer of cuboidal epithelial-type cells and an outer layer of myoepithelial cells with clear or eosinophilic cytoplasm.
