ABSTRACT
The novel coronavirus (SARS-CoV-2) pandemic has influenced the timeliness of care for patients with both common and rare conditions, particularly those affecting high-risk operative sites such as the upper aerodigestive tract. Sinonasal undifferentiated carcinoma (SNUC) represents a rare malignancy of the sinonasal tract, a unique subset of which has never been previously reported in the otolaryngology literature and is characterized by inactivation of the SMARCB (INI-1) tumor suppressor gene. This subtype exhibits a particularly poor prognosis and is characterized pathologically by its rhabdoid appearance. Here we present the case of an individual who was diagnosed with a sinonasal mass during the SARS-CoV-2 pandemic, which was ultimately found to be SMARCB (INI-1)-deficient sinonasal carcinoma. Advanced imaging was deferred in the interest of limiting the patient's exposure to the virus, and expedited operative management was performed which facilitated prompt referral for adjuvant chemoradiation. The SARS-CoV-2 pandemic presents unique challenges, but the work-up of high-risk lesions must be prioritized; this continues to be paramount as SARS-CoV-2 resurges in many cities across the USA.
