 A subset of poorly differentiated carcinomas is characterized by the translocation t(15;19)(q13;p13), resulting in a BRD4/NUT fusion gene.     ///    "The findings show that t(15;19)-BRD4/NUT-positive tumors may arise in locations more typical for other pediatric tumors, such as Ewing sarcoma, and that they not always display epithelial differentiation. "    ///    We here present the successful treatment of a 10-year-old boy who presented with a BRD4/NUT-positive undifferentiated tumor in the iliac bone.
