case_images: Computed tomography showed complete opacification of the right maxillary sinus, obstruction of the right ostiomeatal complex, and soft tissue density in the right nasal passage (Figure 1).
case_images: Right nasal lesion. Hematoxylin and eosin stain. Much of this polypoid tumor had areas lined by mucin-containing cells (100x).

case_images: There was invagination of the surface epithelium into the underlying stroma resulting in nested aggregates of bland glandular and mucinous cells and focally benign squamous epithelium (Figure 2).
case_images: Right inferior meatus mass. Hematoxylin and eosin stain. Gland-like structure lined by one or more layers of cells, with mucinous, vacuolated cells predominating towards the lumen. The nuclei are bland (630x).
