OBJECTIVE
To study the clinicopathologic features and differential diagnosis of atypical teratoid/rhabdoid tumor (AT/RT) occurring in the central nervous system.
METHODS
Two cases of AT/RT were studied by hematoxylin-eosin, reticulin and immunohistochemical staining. The clinical and pathologic
Atypical teratoid/rhabdoid tumors are rare malignant pediatric brain tumors. This study was performed to characterize the clinicopathologic and neuroradiologic characteristics of atypical teratoid/rhabdoid tumors from 8 patients, including 5 male and 3 female infants (median age, 67 months).
A typical teratoid/rhabdoid tumor (AT/RT) is a highly malignant childhood brain tumor. Most AT/RTs are shown to contain chromosome 22 mutation in the region of hSNF5/INI1 gene, whose protein product participates in chromatin remodeling. Although the presence of this mutation is well described,
OBJECTIVE
To study the clinicopathologic features, immunohistochemical findings, diagnosis and differential diagnosis of atypical teratoid/rhabdoid tumors (AT/RT) of central nervous system in childhood.
METHODS
The clinicopathologic data, morphologic features and immunophenotypes were reviewed in 6
High-molecular-mass alkaline phosphatase (H-Mr AP) was detected in sera from children with solid tumors without liver metastases. H-Mr AP activities were determined by a liquid chromatographic and an electrophoretic method. In 5 out of 10 cases with solid tumors--Ewing sarcoma (n = 2), neuroblastoma
Malignant rhabdoid tumors (MRTs) are highly aggressive pediatric tumors associated with loss of expression of SMARCB1, commonly occurring in the central nervous system [referred to as atypical teratoid/rhabdoid tumors (AT/RTs)] and in the kidney and soft tissues. Histologically, MRTs are
The homeodomain transcription factor, NANOG, along with OCT3/4 (POU5F1) and SOX2, is part of the core set of transcription factors that maintain embryonic stem cell self-renewal and pluripotency. Expression of NANOG has been detected in fetal germ cells and in gonadal germ cell tumors. To assess the
