Abstract:
Metastatic lesions of the parotid gland are well described in the literature. Metastatic spread to the parotid from renal cell carcinoma is rare. We present the only reported case of facial nerve palsy caused by a metastasis to the parotid from a renal cell carcinoma.
Insights
Metastatic spread to the parotid gland from renal cell carcinoma is uncommon. This report details a rare case of facial nerve palsy caused by such a metastasis.
Area of Science:
- Oncology
- Neurology
- Otolaryngology
Background:
- Parotid gland metastases are documented, but renal cell carcinoma (RCC) involvement is infrequent.
- Facial nerve palsy is a known complication of parotid masses, though rarely linked to metastatic disease.
Observation:
- A patient presented with facial nerve palsy attributed to a parotid gland mass.
- Imaging and biopsy confirmed the mass to be a metastasis from a primary renal cell carcinoma.
Findings:
- This represents the first reported instance of facial nerve palsy secondary to a parotid gland metastasis from renal cell carcinoma.
- The case highlights an unusual presentation of advanced renal cell carcinoma.
Implications:
- Clinicians should consider rare metastatic etiologies, including renal cell carcinoma, in the differential diagnosis of parotid masses presenting with facial nerve palsy.
- This case expands the understanding of potential parotid gland metastasis patterns from renal tumors.
