Abstract
In African studies on salivary gland tumours, there are considerable epidemiological differences in different parts of the continent. There is no study of salivary gland tumours from the second largest hospital in Ghana, Komfo Anokye Teaching Hospital. Aim: This study was to look at the prevalence and demographic distribution of salivary gland tumours at the Komfo Anokye Teaching Hospital (KATH). Method: Histopathologically diagnosed salivary gland tumours of consecutive patients were evaluated. The study duration was from 1999 to 2010 October. Result: The total number of salivary gland tumours were 121. Male to female ratio was 1.75:1. Out of the total of 34 salivary malignancies seen, male to female ratio was 1.8:1. Malignant tumour was 28.1% while 71.9% were benign. Mean age for malignancy was 53.5 years (SD = 9.7) and that for benign was 35.5 years (SD = 8.2). Conclusion: The commonest benign tumour of the parotid was Pleomorphic adenoma (48.3%) which is consistent with most of the African and western reports. Warthin’s tumour prevalence was higher than most of the studies from Africa.
Highlights
Salivary gland neoplasms are remarkable for their histological diversity and pose a particular challenge to the pathologist because of their complex classification and the rarity of several varieties [1,2]

Summary
Salivary gland neoplasms are remarkable for their histological diversity and pose a particular challenge to the pathologist because of their complex classification and the rarity of several varieties [1,2]. Most publications in the literature on major and minor salivary gland tumours, find it difficult to evaluate the real frequency and site distribution of salivary gland tumours [2,3]. They are relatively rare, accounting for approximately 2% to 10% of all head and neck tumours [4] worldwide and are more commonly found in the parotid gland. Studies in parts of Nigeria and other parts of Africa show salivary gland neoplasm to constitute between 2.8% and 10% of all Head and Neck malignancies [5,6]. There is no study of salivary gland tumours from the second largest hospital in Ghana, Komfo Anokye Teaching Hospital
