Spindle cell rhabdomyosarcoma of bone with <i><scp>FUS</scp>–<scp>TFCP</scp>2</i> fusion: confirmation of a very recently described rhabdomyosarcoma subtype

Abstract

Spindle cell rhabdomyosarcomas carrying the FUS-TFCP2 fusion are very rare rhabdomyosarcoma variants with osseous predilection. The classification and differential diagnosis of this unusual molecular variant of spindle cell/sclerosing rhabdomyosarcoma are discussed.
