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.
