Sinonasal adenocarcinomas are tumors of the salivary glands and account for 5-10% of sinonasal malignancies in the United States but are more common in Europe. An association with the dust encountered by woodworkers and in the leather industry is noted[i] [ii]. Overall sinonasal adenocarcinomas are resected, usually endoscopically,[iii] with adjuvant therapy added based on tumor extent, final histology, and margins.
