Masseter Muscle Metastasis of Renal Cell Carcinoma: A Case Report and Literature Review.

ABSTRACT:

Background

Patients with renal cell carcinoma are often troubled by metastases, but masseter muscle metastases are particularly rare.

Case presentation

We reported a 76-year-old male who did not show any recurrence and metastasis after the nephrectomy until 5 years later. The metastatic mass was found with the protrusion of masseter muscle area. Computed tomography and ultrasonography indicated a hypervascular mass, and pathology confirmed the masseter muscle metastasis of renal cell carcinoma. Complete metastasectomy was performed with the preserval of facial function and appearance. No local recurrence or distant metastasis was found in follow-up.

Conclusion

Our report indicates masseter muscle can be a metastatic site of renal cell carcinoma, regardless of its rari
