A rare case of rhabdomyosarcoma identified in a VRAM flap after lower extremity reconstruction

Spindle cell sclerosing rhabdomyosarcoma (sc-RMS) is an extremely rare soft tissue tumor. We report an unusual case of sc-RMS in a 36-year-old patient whose tumor arose in a rectus abdominis muscle free flap that had been used for lower extremity reconstruction 18 years previously. After surgical excision of the tumor and immediate reconstruction, the patient has remained in remission and has full function of his lower extremity six months after diagnosis and treatment.
