Case report 708: Metastasis of renal cell carcinoma to skeletal muscle (right trapezius).
A patient is described who presented with a painful soft-tissue mass in the region of the right shoulder 10 months following nephrectomy for carcinoma. This mass proved to be a metastasis to skeletal muscle. A full metastatic work-up demonstrated no other detectable lesions. Metastases to skeletal muscle are rare, regardless of the site of origin, and their true incidence is difficult to determine since they rarely present clinically and are not routinely searched for, even on autopsy.
