Abstract:

Objective　To analyse the clinical and pathological characterstics ofminor salivary gland tumors.Methods　Aret- rospective 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 ofminor salivary gland tumors, 265 caseswere benign, 350 casesmalignant. 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 malig- nant tumors were 40·9 and 49·1 years old, respectively (P<0·05).Conclusion　We consider extraordinary manifestation as histopathology, tumor, primary location, age and sex, presentingthe results of a reviewof our experiencewiththose minor salivary gland tumors.
