Background
: To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso,
Chile.
Material and Methods
: Retrospective review of salivary gland tumours diagnosed between the years 2000 and
2011 from four local pathology services. Information on demographics and histopathology were retrieved from
the medical records.
Results
: The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000
persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The
most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%)
and mucoepidermoid carcinoma was the most common malignant tumour (7.2%).
Conclusions
: Salivary gland tumours are uncommon neoplasms that usually arise in the parotid gland. Pleomor-
: Salivary gland tumours are uncommon neoplasms that usually arise in the parotid gland. Pleomorphic adenoma and mucoepidermoid carcinoma were the most common benign and malignant tumours reported
in this series
