Definition
A highly malignant tumor that primarily affects infants and young children. Rhabdoid cells contain large nuclei with prominent nucleoli and abundant eosinophilic cytoplasm that often contains filamentous cytoplasmic inclusions. In tumors of the central nervous system (CNS), areas of rhabdoid cells may be seen in juxtaposition to areas of primitive neuroepithelial cells resembling primitive neuroectodermal tumor, as well as mesenchymal tissue and/or epithelial tissue. The designation atypical teratoid/rhabdoid tumor (AT/RT) is used to describe the CNS tumor.
Characteristics
The true incidence of rhabdoid tumors in the population is not known due to the fact that many of these malignancies, especially in the brain, have been misdiagnosed. The most common sites of presentation for rhabdoid tumor are the kidney and brain. Rhabdoid tumors account for approximately 1–2 % of childhood renal tumors and 2 % of pediatric CNS tumors (Brain Tumor). Extrarenal tumors are less common and...
