Introduction:

Salivary gland tumors are rare malignant neoplasms, with a higher incidence in the parotid gland. Despite their low incidence, the possible complications derived from them can lead to high comorbidity in patients.

Methods:

We conducted a retrospective, observational and descriptive study of 105 patients diagnosed with malignant neoplasms of the salivary glands at the Hospital Universitario La Paz. 102 correspond to primary tumors and 3 of them are metastases of pulmonary origin.

Results:

In our series the parotid gland is the most frequent site. Histologically, adenoid cystic carcinoma is the most common tumor. The 75.23 % of the patients were diagnosed with cytology by fine needle aspiration and puncture (FNA), and the remaining cases with biopsy. The most indicated treatment was surgery, especially for tumors of epithelial lineage. Some 33.5 % received adjuvant treatment. Some 18 % of the patients who suffered post-surgical complications presented facial paralysis. During the course of the disease, 23.80 % of the total developed distant metastases, the lung being the most affected organ. Of the patients, 26.66 % suffered at least one recurrence. Survival at 2 years was 87.6 % and at 5 years 75.3 %.

Discussion:

Unlike other studies, in our case the most frequent lineage of salivary glands tumors is adenoid cystic carcinoma. This could be explained because our hospital is a reference in facial paralysis. One of the most important points in the management of these patients is not only the local and distant control of the tumor, but also the treatment of possible sequelae.
