Background: Mucoceles most commonly occur in the frontal sinuses and can expand the sinus cavity, invade surrounding tissues, and cause health problems like brain abscesses and vision loss. The common causes of mucoceles include previous sinus surgery, trauma, and chronic inflammatory diseases like acute and chronic rhinosinusitis. Case presentation: A 38-year-old man with forehead and medial cantus swelling was admitted to Loghman Hakim Hospital. He reported no history of chronic inflammatory disease, trauma or surgery. patient had a satisfactory postoperative period and was discharged two days later with good cosmetic results. Discussion: Mucoceles form when a sinus opening is blocked, causing a buildup of mucus. They are most commonly found in the forehead region and can cause symptoms such as headaches, eye swelling, visual disturbances, and difficulty breathing. CT scans are essential for diagnosis, but MRI is superior for distinguishing mucoceles from other masses. Endoscopic surgery is the preferred treatment with low risk of recurrence. Conclusion: A middle-aged male patient was diagnosed with a large frontoethmoidal mucocele spontaneously with no prior surgery, trauma or chronic inflammatory disease history.
