Sinonasal malignant tumors constitute less than 1% of all neoplasms and approximately 3% of those of the upper aerodigestive tract.1 Sinonasal malignant neoplasms most commonly affect the maxillary sinuses (approximately 60%), followed by the nasal cavity (approximately 22%), ethmoidal sinus (approximately 15%), and frontal and sphenoid sinuses (<3%).1 Sinonasal neoplasms are diverse, with most being squamous cell carcinoma or variants (55%), followed by nonepithelial neoplasms (20%), glandular tumors (15%), undifferentiated carcinoma (7%), and miscellaneous tumors (3%).1 We describe an exceedingly unusual case of ethmoidal lipid-rich carcinoma with focal glandular structures. To our knowledge, such a case has not been documented in the literature to date.
