Summary
Metastasis of renal cell carcinoma (RCC) to the larynx is rare. This case details an isolated laryngeal tumor appearing 7 years post-kidney removal, suggesting local excision may yield good outcomes.
Area of Science:
- Oncology
- Head and Neck Surgery
- Urologic Oncology
Background:
- Renal cell carcinoma (RCC) metastasis to the head and neck is uncommon.
- Laryngeal metastasis from RCC is exceptionally rare, often presenting before the primary tumor diagnosis.
Observation:
- This report details an unusual case of isolated supraglottic laryngeal metastasis from RCC.
- The metastasis manifested 7 years after a radical nephrectomy for the primary kidney cancer.
- There was no evidence of recurrence between the nephrectomy and the laryngeal metastasis detection.
Findings:
- This is the first reported instance of an isolated supraglottic laryngeal RCC metastasis occurring 7 years post-nephrectomy.
- The patient's laryngeal lesion was the sole site of recurrence.
- Local excision of the isolated laryngeal metastasis was performed.
Implications:
- Isolated laryngeal metastases from RCC, though rare, can occur long after nephrectomy.
- Early detection and local excision of such isolated lesions may lead to a favorable prognosis.
- This case highlights the importance of considering metastatic disease in the differential diagnosis of laryngeal tumors, even years after primary cancer treatment.
