Aim of the study: The aim of this case presentation is to emphasise the importance of meticulous history-taking and physical examination, and increase the awareness of various possibilities for the diagnosis and management of patients with unilateral cheek swelling. Maxillary mucocele is a rare benign cystic lesion of paranasal sinuses. It may be associated with varying symptoms, and patients commonly present with compression symptoms during their first visit, as the maxillary sinus is adjacent to vital structures, notably the orbit and skull base. Case report: Herein, we present the case of a middle-aged man who presented with painless unilateral cheek swelling that turned out to be maxillary mucocele. Conclusions: Presentation of maxillary mucocele often mimics cancerous lesion types. Thorough assessment and proper imaging help to guide otorhinolaryngologists towards making an accurate diagnosis and initiating prompt management.
