[A retrospective study on 615 cases of minor salivary gland tumors].
OBJECTIVE
To analyse the clinical and pathological characteristics of minor salivary gland tumors.


METHODS
A retrospective analysis on 615 cases of intraoral minor salivary gland tumors from 1990-2002 with a confirmed pathologic diagnosis was carried out.


RESULTS
In 615 cases of minor salivary gland tumors, 265 cases were benign, 350 cases malignant. Pleomorphic adenoma was the most common entity and accounted for 81.1% of all benign tumors. Adenoid cystic carcinoma comprised 32.9% of the malignant sample and was the most frequent malignant tumor. The principal location was the palate. Female was a little more of the benign and a male prevalence was observed on the malignant tumor. The mean age of patients with benign and malignant tumors were 40.9 and 49.1 years old, respectively (P < 0.05).


CONCLUSIONS
We consider extraordinary manifestation as histopathology, tumor, primary location, age and sex, presenting the results of a review of our experience with those minor salivary gland tumors.
