Malignant rhabdoid tumor (MRT), described for the first time in 1978 in the kidney, has rarely been reported in other organs including the brain and has involved adults in only 3 cases. We described a case of MRT in a 32-year-old woman who presented with severe headache, nausea and sudden onset of
Atypical teratoid/rhabdoid tumor (AT/RT) is a rare, highly malignant, true rhabdoid tumor in the central nervous system predominantly presenting in young children.AT/RT typically shows rhabdoid cells which can also be seen in other tumors, but it is differentiated from other tumors by the specific
Rhabdoid tumors of the central nervous system are uncommon, aggressive childhood malignancies. The 13 described adult cases comprise both primary CNS tumors and malignant transformation of previously existing gliomas, meningiomas, and astrocytomas. Central nervous system rhabdoid lesions of adults
Rhabdoid tumors of the brain are rare with an invariable dismal prognosis despite treatment. This is the case of a 3 year old boy who presented lethargy, somnolence, nausea, vomiting, and headaches one week prior to hospitalization. A posterior fossa tumor with hydrocephalus was noted on a head
OBJECTIVE
In vitro fertilization (IVF) is increasingly used for the treatment of infertile couples worldwide. The association between IVF and cancer risk in offspring is conflicting. We present a case of atypical teratoid/rhabdoid tumor (AT/RT) in a girl conceived by IVF and present results of
Background: Atypical teratoid/rhabdoid tumor (AT/RT) is a rare tumor that is most frequently encountered in the pediatric patient population. AT/RT accounts for approximately 1-2% of all pediatric central nervous system (CNS) tumors and
The authors present the case of a rare extraventricular, intraparenchymal choroid plexus carcinoma (CPC). This 6-year-old girl presented to the emergency department with a 1-week history of headaches, nausea, and vomiting. Imaging studies revealed an intraaxial cystic and solid mass located in the
OBJECTIVE
Atypical teratoid/rhabdoid tumors (ATRTs) represent a relatively newly categorized neoplastic entity. They commonly present in childhood, and have a rapidly progressive clinical course with a survival time of less than 1 year. Treatment regimens have been nonuniform. In this retrospective
BACKGROUND
Atypical teratoid rhabdoid tumor is a rare malignant neoplasm that represents 1%-2% of all pediatric central nervous system tumors. Immunohistochemistry plays an important role in establishing the diagnosis with a loss of INI-1 staining in tumor cells. In this case report, we describe a
Purpose: The cyclin-dependent kinase (CDK) 4/6 inhibitor, ribociclib (LEE011), displayed preclinical activity in neuroblastoma and malignant rhabdoid tumor (MRT) models. In this phase I study, the maximum tolerated dose (MTD) and recommended phase II dose (RP2D), safety, pharmacokinetics (PK), and
BACKGROUND
Proton beam therapy (PBT) for pediatric CNS malignancies may reduce late toxicity, but acute toxicity is not well defined. We examined acute toxicity for children with CNS malignancies treated with PBT.
METHODS
We conducted a retrospective review of 48 children with malignant brain tumors
Ifosfamide/mesna was given to 97 patients who had malignant solid tumors diagnosed before they were 21 years of age. Patients received 1.6 g/m2 ifosfamide daily x 5, given i.v. over 15 min, followed by 400 mg/m2 i.v. mesna at 15 min and 4 and 6 h after ifosfamide. Responses were noted in patients
Germ cell tumors, which constitute approximately 3-5% of tumors of the central nervous system (CNS), can be subdivided into germinomas, embryonal carcinomas, yolk sac tumors, choriocarcinomas, teratomas and mixed germ cell tumors. The diagnosis of intracranial germ cell tumor is based on the
OBJECTIVE
The salvage therapy of recurrent embryonal brain tumors in children is disappointing. Temozolomide is a newly developed chemotherapeutic agent in central nervous system tumors. This study analyzed the efficacy of temozolomide on the treatment of recurrent embryonal brain tumors in
Desmoplastic myxoid tumor (DMT), SMARCB1 mutant is a recently proposed new entity that mainly occurs in the pineal region and has epigenetic features similar to those of atypical teratoid/rhabdoid tumors (AT/RT)-MYC and poorly differentiated chordomas. Herein, we present a new case of a 33-year-old
