Desmoplastic Small Round Cell Tumor


  • Caused by the reciprocal chromosomal translocation, t(11;22)(p13;q12)
  • Gene fusion product is chimeric protein EWS-WT1
    • Functions as a novel transcription factor that activates expression of target genes
      • PDGF-A expressed
        • Potent growth factor for fibroblasts
          • Linked to the characteristic desmoplasia
    • (EWS gene on chromosome 22)
    • (WT1 gene on chromosome 11)
      • Tumor suppressor involved in the development of Wilms' tumor
