A DESCRIPTIVE STUDY OF HISTOPATHOLOGICAL FEATURES OF SALIVARY GLAND TUMOURS IN JOS UNIVERSITY TEACHING HOSPITAL (JUTH)
Abstract
BACKGROUND
Salivary gland tumour is a common head and neck tumour said to constitute 2.8% to 10% of all head and neck tumours in certain African studies and 8.0% to 10.5% of all head and neck tumours in the Western World. However, there are not many histopathological studies addressing the issue.
AIM
This study was carried out to describe the morphologic pattern, age and sex distribution of salivary gland tumours in Jos.
METHOD/MATERIALS
This was a descriptive study of all histologically confirmed salivary gland tumours over a period of 10 years. Histologic classification was made based on the World Health Organization (WHO) classification of salivary gland tumours and staging done using the TNM staging according to the American Joint Committee for Cancer Staging (AJCC)
RESULTS
A total of 202 salivary gland tumours were diagnosed; 128 were benign, 74 were malignant constituting 63% and 37% respectively. Pleomorphic adenoma was the commonest benign tumour and muco-epidermoid Carcinoma the commonest malignant tumour.
CONCLUSION
In this study, benign lesions are observed to be commoner than malignant ones, are mostly in major glands and in 3rd – 4th decade. While the malignant lesions were commoner in the 5th decade and above. Late presentation is our experience in our environment probably due to slow growth and painless nature of most lesions, high level of illiteracy, lack of adequate specialist hospitals and a general low socioeconomic situation in the country.
