NCIt definition : An aggressive malignant embryonal neoplasm usually occurring during childhood. It
is characterized by the presence of large cells with abundant cytoplasm, large eccentric
nucleus, and a prominent nucleolus and it is associated with abnormalities of chromosome
22. It can arise from the central nervous system, kidney, and the soft tissues. The
prognosis is poor.;
Alternative definition : NCI-GLOSS: A malignant tumor of either the central nervous system (CNS) or the kidney.
Malignant rhabdoid tumors of the CNS often have an abnormality of chromosome 22. These
tumors usually occur in children younger than 2 years.; NICHD: Extremely aggressive malignancies that generally occur in infants and young
children. The most common locations are the kidney and central nervous system (CNS),
although they can also arise in most soft tissue sites. Approximately two-thirds of
patients will present with advanced-stage disease. Rhabdoid tumors of the kidney tend
to metastasize to the CNS and lungs. Rhabdoid tumors are associated with mutations
of SMARCB1 (INI-1), a tumor suppressor gene.; NCI-GLOSS: An aggressive cancer of the central nervous system, kidney, or liver that
occurs in very young children.;
