Metastatic Renal Cell Carcinoma of the Head and Neck: A Case Series.

BACKGROUND

Renal cell carcinoma (RCC) accounts for over 80% of malignant tumors arising from the kidney. However, metastatic RCC to the head and neck is a relatively rare entity.

CASE PRESENTATION: We describe three patients with metastatic RCC to the head and neck with the involvement of the parapharyngeal space, the level V region of the neck, and the maxillary sinus.

CONCLUSION

Metastatic RCC in the head and neck is uncommon; however, it must be taken into consideration given a patient with a history of RCC. Multiple pathways allow for the spread of RCC to the head and neck region. Treatment options include mastectomy or local radiation and systemic chemotherapy.
