As highlighted by Reference (12), carcinomas and mesenchymal tumors with SWI/SNF dysfunction frequently exhibit a discohesive epithelioid or rhabdoid phenotype, necessitating a targeted immunohistochemical evaluation of INI-1 (SMARCB1) and BRG1 (SMARCA4) during diagnostic workup. Here, SMARCA4 is linked to mesenchymal cell neoplasm.
