Pathology teach and tell: central nervous system atypical teratoid/rhabdoid tumor.

Atypical teratoid/rhabdoid tumor (AT/RT) is extremely malignant, highly aggressive primitive central nervous systemneoplasm of infancy with very poor prognosis. Histologically, AT/RT is defined as a polymorphous neoplasm often featuring rhabdoid, PNET, mesenchymal, and epithelial components.
