title: Renal cell carcinoma presenting as a skeletal muscle mass: a case report.
abstract: A 62-year-old man presented with a 17-month history of a slowly enlarging biceps muscle mass. A diagnosis of metastatic renal cell carcinoma was made in the outpatient department using a soft tissue biopsy needle. Despite the rarity of muscular metastases in renal cell carcinoma, early definitive diagnosis of soft tissue masses is recommended.
