title: Atypical presentation of primary giant nasal septal mucopyocele.
abstract: Mucoceles are expansile, encapsulated, benign cystic lesions with the potential for adjacent bony remodeling and resorption. Previous nasal surgery, recurrent infections, allergies, and facial traumas are all possible causes of mucoceles involving mainly paranasal sinuses. When the mucocele is infected, it is referred to as mucopyocele. Nasal septal mucoceles seen in only very seldom cases might develop from pneumatized and infected nasal septa. In the current article, we present an interesting primary giant septal mucopyocele that destroys all paranasal cells as a tumoral lesion. The perpendicular plate of ethmoidal bone, vomer, and bilateral anterior and posterior ethmoidal cells were destroyed by mucopyocele. The nasal cavity was totally obstructed by lesions on both sides. On the left side, the lesion also eroded the left lateral nasal wall causing external swelling at the medial canthal region. This is the first case of a giant septal mucopyocele of its kind in the literature. Although nasal septal mucocele is very rare, it should be considered in differential diagnosis of intranasal masses.
