Atypical teratoid/rhabdoid tumor - A stereogram unveiled

Atypical teratoid/rhabdoid tumor of the central nervous system has successf ully emerged from inclusion as a form of medulloblastoma to a distinctive e ntity over the past decade. This event has more than nosological importance in that the five-year survival rate for medulloblastoma is considerably be tter than for atypical teratoid/rhabdoid tumor which is uniformly poor. The relationship of the central nervous system neoplasm to malignant rhabdoid tumor of the kidney, beyond sharing some histologic features and a genetic linkage to chromosome 22, needs further exploration.
