According to a report by Lee et al. [7], regarding the cell morphology of SMARCB1-deficient sinonasal carcinoma, basaloid cell morphology was the most common cell morphology (68/192 cases, 35.4%), followed by plasmacytoid/rhabdoid cell morphology (37/192 cases, 19.3%). This evidence concerns the gene SMARCB1 and nasal cavity and paranasal sinus carcinoma.
