Most of the patients complain primarily of the ophthalmic symptoms. However, the present case reminds us that frontal mucocele is one of the differential diagnoses for a subcutaneous mass on the forehead. Authors report an unusual case of frontal mucocele in a 64 years old Iranian male who presented with painless slowly progressive subcutaneous swelling of ten-year duration on the forehead. Endoscopic marsupialization, decompression of the mucocele, removal of the sinus mucosa and widening of ostium was performed. The case is discussed and the pertinent literature is reviewed. https://biomedpharmajournal.org/vol8marchspledition/frontal-mucocele-presenting-as-a-subcutaneous-giant-mass/ Giant Mucocele Frontal Sinus Subcutaneous Mass Fess
