Many cases have a pure rhabdoid morphology although they can be combined with more conventional forms of colorectal carcinomas (CRC) suggesting that they should be interpreted as rhabdoid carcinomas and not rhabdoid neoplasm equivalents of pediatric malignant rhabdoid tumors of the kidney and of the soft parts characterized by genetic inactivation of SMARCB1 (SNF5, INI-1), a component of the switching/sucrose nonfermenting (SWI/SNF) chromatin remodeling complex [2]. Here, SMARCB1 is linked to colorectal carcinoma.
