Switch/sucrose non-fermentable-related matrix-associated actin-dependent regulator of chro-matin subfamily B member 1 (SMARCB1)-deficient sinonasal carcinoma is a rare subtype ofsinonasal undifferentiated carcinoma (SNUC). Due to the highly aggressive nature of the dis-ease course, it is important to diagnose early and use multimodal treatments in the course ofthe disease. Two main morphologic patterns are commonly identified under the microscope:plasmacytoid/rhabdoid and basaloid. Furthermore, it demonstrates a total absence of integraseinteractor 1 expression upon immunohistochemical staining. Here, we present two cases ofSMARCB1-deficient sinonasal carcinoma with contrasting outcomes.
