Salivary gland type tumours of the lung

Benign

Monomorphic adenoma2, oncocytoma1,4, myoepithelioma3 and adenomyoepithelioma5 are extremely rare primary lung tumours

Variable behaviour

Pleomorphic adenoma

Malignant

Mucoepidermoid carcinoma, adenoid cystic carcinoma and epithelial-myoepithelial carcinoma all occur in the lung and resemble the corresponding salivary gland tumours. Other malignant salivary gland type tumours have occasionally been reported from the bronchi. These include acinic cell tumour, carcinoma ex pleomorphic adenoma and malignant endobronchial myxoid tumour.

Both myoepithelioma and malignant mixed tumour have been reported arising from pulmonary hamartoma.
