Abnormalities of SMARCB1 (INI1), which encodes a member of the SWI/SNF pathway, are found in neoplasms with rhabdoid morphology, such as malignant rhabdoid tumour of the kidney and atypical teratoid/rhabdoid tumour of the central nervous system. SMARCA4 (BRG1), which encodes another member of the SWI/SNF pathway, and which is mutated in almost all small‐cell carcinomas of the ovary, hypercalcaemic type, has been investigated in endometrial carcinomas, and mutations with resultant loss of immunohistochemical staining have been demonstrated in some endometrial undifferentiated carcinomas/dedifferentiated carcinomas. The aim of this study was to evaluate immunohistochemical expression of SMARCA4, SMARCB1 and SMARCA2 in a cohort of undifferentiated endometrial carcinomas, and to correlate expression of these markers with rhabdoid morphology and clinical outcome.
