Primary pulmonary salivary gland-type tumors are rare and characterized by a specific clinico-pathological manifestation. They are proximal tumors affecting young subjects and not associated with smoking. For optimal management, it is important to distinguish them from other bronchopulmonary tumors, with which they don´t share either biology or treatment and outcome. We conducted a retrospective study, including all primary malignant salivary gland-type tumors of the lung, over a period of 32 years, from January 1987 to December 2019. We collected data from the medical records of 10 patients: 5 men and 5 women (sex ratio 1). The average age of our patients was 47.4 years. In all cases radiological examinations showed proximally located nodular tumor ranging in size from 1 to 5.8 cm. Histological examination objectified mucoepidermoid carcinoma (6 out of 10 cases). All patients had localized or locally advanced tumors, with the exception of one case of metastatic mucoepidermoid carcinoma. Pulmonary salivary gland-type tumors correspond to a heterogeneous group of tumours. They are not very aggressive but are associated with a high frequency of recurrences and late metastases, requiring long-term monitoring.

D008949 Adenoma, Pleomorphic A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.

D002277 Carcinoma A malignant neoplasm made up of epithelial cells tending to infiltrate the surrounding tissues and give rise to metastases.

D003528 Carcinoma, Adenoid Cystic Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves.

The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
