BACKGROUND: Salivary gland tumours consist of a variety of benign and malignant lesions with different patterns of presentation. The pattern of presentation in the University of Port Harcourt Teaching Hospital (UPTH) has not been reported in English literature.
OBJECTIVES: The objective of this study is to determine the age, gender, sites and histological types of salivary gland tumours seen in the UPTH and to compare their pattern of presentation to those reported.
MATERIALS AND METHODS: The records of all patients diagnosed of salivary gland tumours at the Oral Pathology Department of UPTH from January 2008 to December 2015 were retrospectively reviewed. The variables analyzed from the case notes of these patients were; the age, gender, site and histological types.
RESULTS: The total number of biopsies during this period was 374 and 29 (7.8%) of patients presented with salivary gland tumours, consisting of 20 (69%) female and 9 (31%) male. The age of the patients range from 10-68 years with a mean age of 44.3 (±15.3 SD) years. Over 70% of the patients were above 30 years in age. The most common site was the palate with 18 (62.1%) cases and the least affected site was the tongue with 1 (3.4%) case. Majority of the salivary gland tumours were malignant with 28 (96.6%) cases, while only 1 (3.4%) case was benign. Mucoepidermoid carcinoma was the most prominent tumour followed by lymorphous low grade adenocarcoma.
CONCLUSION: Salivary gland tumours are relatively rare in our environment especially the benign lesions. Most cases affected patients above 30 years of age and the minor salivary glands of the palate are mostly affected. Mucoepidermoid carcinoma was the most common histologically diagnosed lesion.
