Childhood central nervous system (CNS) atypical teratoid/rhabdoid tumor (AT/RT) was first described as a discrete clinical entity in 1987 based on its distinctive pathological and genetic characteristics. Before then, it was most often classified as a medulloblastoma, CNS primitive neuroectodermal tumor (CNS PNET), or choroid plexus carcinoma.Atypical Teratoid-Rhabdoid Tumor.

Atypical Teratoid/ Rhabdoid Tumor (AT/RT) is a rare central nervous system tumor of the brain and spinal cord, which may also originate in other organs and tissues. It usually occurs in children younger than three years of age, although it can occur in older children and adults. About half of these tumors form in the cerebellum or brain stem ...Background Extradural malignant rhabdoid tumors of the spine are highly malignant and invasive tumors (WHO grade IV) with poor prognosis, most frequently occurring in young children before 2 years of age.

Introduction. Atypical teratoid/rhabdoid tumor (ATRT) is a highly malignant central nervous system tumor characterized by loss of SMARCB1/INI1 protein expression [].ATRT comprises three molecular groups, i.e., ATRT-SHH, ATRT-TYR and ATRT-MYC [].ATRT-SHH represents the largest molecular group [] and overexpression of members of the sonic hedgehog (SHH) and Notch signaling pathway are a ...Abstract. Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant central nervous system cancer arising in infants and younger children, historically considered to be homogeneous, monogenic, and incurable. Recent use of intensified therapies has modestly improved survival for ATRT; however, a majority of patients will still succumb ...INTRODUCTION. Central nervous system (CNS) atypical teratoid/rhabdoid tumor (ATRT) is highly malignant. ATRT accounts for 2%-3% of childhood CNS tumors, but up to 20% of malignant CNS tumors in patients younger than 3 yr of age (1, 2).The prognosis of ATRT is extremely poor because these tumors often rapidly relapse or progress despite aggressive surgery, conventional chemotherapy, and/or ... ….

Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant tumor that may not only contain rhabdoid tumor cells but also poorly differentiated small-round-blue cells as well as areas with mesenchymal or epithelial differentiation. Little is known on factors associated with histopathological diversity. Recent studies demonstrated three ...Abstract. Atypical teratoid rhabdoid tumors (AT/RT) are malignant central nervous system (CNS) tumors that occur mostly in young children and have historically carried a very poor prognosis. While recent clinical trial results show that this tumor is curable, outcomes are still poor compared to other central nervous system embryonal tumors.

It is characterized by the presence of rhabdoid cells in combination with loss of either the INI1 or BRG1protein from the tumor cells.
