Lung carcinomas of the salivary gland type are also known as salivary gland–type tumours of the lung (SGTTLs) or bronchial gland neoplasms.
The usual consignation to the group of non-small cell lung cancer (NSCLC) may be unfortunate because the clinical behavior of SGTTLs can be quite different from that of conventional lung cancers 5.
SGTTLs are thought to account for 0.1-2% of all lung carcinomas.
These tumours occur primarily in the central airways and are thought to originate from submucosal glands 5:
- mucoepidermoid carcinoma (MEC) of the lung: most common type
- adenoid cystic carcinoma (ACC) of the lung: second most common type
- acinic cell carcinoma of the lung (Fechner tumour)
- epithelial-myoepithelial carcinoma of the lung: one of the most unusual primary tumours of the lung
Only a few cases of the latter two lesions have been reported in the literature.
