Background: The spectrum of salivary gland lesions is wide and the relative incidence of neoplastic and non-neoplastic lesions is variable in different studies. Despite the relatively common nature of salivary gland disorders, there is dearth of literature on these lesions, especially in sub-Saharan Africa. We therefore embarked on this study to analyze the differential diagnosis of salivary gland lesions seen and managed at our institution. Methods: A retrospective review of salivary gland disorders that presented at our facility from January 2012 to December 2016 was done. Information on patients’ demographic details, type and location of salivary gland lesion, histologic diagnosis and treatment were retrieved and analyzed with SPSS version 20. Result: A total of 65 patients were treated for salivary gland lesions of various types during the study period. The age of the patients ranged from 3 months to 68 years [mean 33.8 ± 12.3]. Neoplastic lesions [n = 39, 60.0%] were the commonest followed by sialolithiasis [n = 14, 21.5%] while mucous retention/extravasation cysts accounted for 13.9% of the cases. Pleomorphic adenoma was the predominant tumor in this series [87.2%] and the commonest site was the parotid gland [58.8%]. On the contrary submandibular gland appeared to be the commonest site for sialolithiasis [57.1%]. The majority of mucous retention/extravasation cysts occurred in the sublingual gland [55.5%]. Conclusion: Neoplastic lesions remain the commonest salivary gland disorder and pleomorphic adenoma was the most prevalent. Sialolithiasis and mucous cysts are salivary gland lesions with equally wide disease spectrum.
