Endoneural metastasis of the sciatic nerve disclosing the relapse of a renal carcinoma, four years after its surgical treatment.
METHODS
To report on an exceptional case of renal metastasis. Indeed, endoneural metastases of peripheral nerves are thought to be exceptional, and such an event has not yet been ascribed to a renal carcinoma.


RESULTS
We report on a sciatica leading to the discovery of a tumour of the right thigh which proved to be an endoneural metastasis of the sciatic nerve from a renal carcinoma surgically removed 4 years before.


CONCLUSIONS
A thorough palpation of peripheral nerve can help recognise such metastases in patients previously diagnosed with renal carcinoma.
