Abstract: Background: Intraoral minor salivary gland tumours (MSGT) are uncommon, with geographic variations in frequency and distribution. This study aims to analyze the clinicopathologic features of these tumours in the Malaysian population. Three major oromaxillofacial referral centers in Malaysia were selected. These centers are Department of Oral Surgery, Hospital Kuala Lumpur, Department of Oral Surgery Queen Elizabeth Hospital, Kota Kinabalu and Department of Oral Pathology Sarawak General Hospital, Kuching. All cases histopathologically recorded as intraoral MSGT from 2000 to 2012 were evaluated retrospectively with regard to patient’s age, ethnicity, gender and tumour location and type. Out of 76 cases of intraoral MSGT, 40.8% were benign and 59.2% were malignant. Pleomorphic adenoma and mucoepidermoid carcinoma (MEC) were the most common benign and malignant tumours, respectively. The palate was the most common site of involvement (46.1%). Male to female ratio was 1:1.8. The mean age of the patients was 45.25±17.5 years for benign and 47.1±18.1 years for malignant tumours. The indigenous people of Sabah and the Malaysian Chinese were most likely to present with intraoral MSGT. Intraoral MSGTs in the present study shows many characteristics similar to other studies.
