Soft tissue metastasis of renal cell carcinoma: A case report

Renal cell carcinoma (RCC) is the most common primary renal malignant neoplasm in adults, accounting for 90% of renal tumours and 2% of all adult malignancies. Distant metastasis has been reported commonly to bone, lung, abdomen, brain etc. Soft tissue and skeletal muscle metastasis is rare. This is the case of a 59 year old female, who presented with a left lower chest wall mass, which was proven to be a metastatic deposit from a clear cell RCC. The rare presentation in skeletal muscle should be suspected, which should also be differentiated from a benign soft tissue tumour.
