The cytomorphologic features and IHC profile of our case were consistent with other reported cases of SMARCA4-UT: (1) moderately cellular aspirate containing dispersed and loosely cohesive malignant cells; (2) malignant cells showing nuclear polymorphism, prominent nucleoli, and scant cytoplasm, with occasional cells exhibiting rhabdoid features; (3) a background of necro-inflammatory debris; (4) the tumor cells were focally highlighted by neuroendocrine markers such as INSM-1; (5) loss of expression of SMARCA4 (BRG1) by IHC. Here, INSM1 is linked to neoplasm.
