An Unusual Case of Type 2 Fronto-Ethmoidal Mucopyocele.

Mucoceles of the paranasal sinuses are epithelium-lined cystic masses that develop when the sinus ostia get obstructed. They most frequently occur in the frontal and ethmoid sinuses. The paranasal sinus mucoceles' proximity to the orbit and skull base renders the patient at risk for substantial morbidity. Mucoceles have reactive bone growth, bleeding, fibrosis, and granulation tissue, which are histological traits of respiratory mucosa. The conventional therapy is surgical excision, with endoscopic procedures becoming more popular. A 60-year-old female patient reported to the ENT outpatient clinic complaining of swelling over the medial aspect of her left eye that had begun slowly and progressed over a year. Although there were no neurological, ocular, nasal, or facial symptoms clinically, radiological and cytological examinations aided us in arriving at the definitive diagnosis. The patient in this scenario had an infected mucocele and left medial canthal swelling with no visual impairment, which made it challenging to reach an accurate diagnosis. However, radiological evaluation and cytological examination focused on establishing a definitive diagnosis.
