Abstract
Objectives: Accurate diagnosis of salivary gland neoplasms (SGN) in many centers in
Africa is limited by poor diagnostic resources and ancillary services. Hence, we have
carried out a multicenter epidemiological study to understand the true burden of
SGN in Nigeria.
Method: In this descriptive cross‐sectional study, we have deployed resources available
to members of the African Oral Pathology Consortium (AOPRC) to examine the
burden of salivary gland lesions in Nigeria, using a multicenter approach. Data from
seven major tertiary health institutions in northern, western, and southern Nigeria
were generated using a standardized data extraction format and analyzed using the
Epi‐info software (Version 7.0, Atlanta, USA).
Result: Of the 497 cases examined across the seven centers, we observed that SGN
occurred more in females than males. Overall, pleomorphic salivary adenoma (PA)
was found to be the most common. PA was found to be the commonest benign SGN
while adenocystic carcinoma (ADCC) was the commonest malignant SGN. Regional
variations were observed for age group, diagnosis, and gender distribution. Significant statistical differences were found between males and females for malignant SGNs (p‐value=0.037).
Conclusion: We found regional variation in the pattern of distribution of SGN in
Nigeria. This is the largest multicenter study of SGN in Nigeria, and our findings are
robust and representative of the epidemiology of this neoplasm in Nigeria.
