1. Low-grade small round cell tumor of the cauda equina with EWSR1-WT1 fusion and indolent clinical course.

    Human Pathology 46(1):153 (2015) PMID 25454478

    We report a case of a longstanding, large tumor involving spinal nerve roots of the cauda equina. The tumor showed small round cells arranged in nests and cords and immunophenotypic features of a glomus tumor, along with infrequent mitoses and a low Ki-67 labeling index, but exhibited some roset...

  8. Towards an international pediatric liver tumor consensus classification: proceedings of the Los Angeles COG liver tumors symposium.

    Modern Pathology 27(3):472 (2014) PMID 24008558

    Liver tumors are rare in children, and their diagnoses may be challenging particularly because of the lack of a current consensus classification system. Systematic central histopathological review of these tumors performed as part of the pediatric collaborative therapeutic protocols has allowed ...
  9. Hepatoblastoma state of the art: pathology, genetics, risk stratification, and chemotherapy.

    Current Opinion in Pediatrics 26(1):19 (2014) PMID 24322718

    As a rare pediatric tumor, hepatoblastoma presents challenges to the individual practitioner as no center will see more than a handful of cases each year. The Children's Hepatic tumor International Collaborative (CHIC) effort has fostered international cooperation in this rare children's tumor, ...

  12. Integrated multimodal genetic testing of Ewing sarcoma—a single-institution experience

    Human Pathology 44(10):2010 (2013)

    Ewing sarcoma (ES) is an aggressive malignant small round cell tumor that arises in bone or soft tissue of adolescents and young adults. A characteristic molecular finding in ES is EWSR1 gene fusion with ETS (erythroblast transformation-specific) family genes including FLI1 (~90%) and ...

    Ewing sarcoma (ES) is an aggressive malignant small round cell tumor that arises in bone or soft tissue of adolescents and young adults. A characteristic molecular finding in ES is EWSR1 gene fusion with ETS (erythroblast transformation-specific) family genes including FLI1 (~90%) and ERG (>5%)....
  14. Genomic heterogeneity of translocation renal cell carcinoma.

    Clinical Cancer Research 19(17):4673 (2013) PMID 23817689 PMCID PMC3882157

    Translocation renal cell carcinoma (tRCC) is a rare subtype of kidney cancer involving the TFEB/TFE3 genes. We aimed to investigate the genomic and epigenetic features of this entity. Cytogenomic analysis was conducted with 250K single-nucleotide polymorphism microarrays on 16 tumor specimens an...
