Renal cell carcinoma (RCC) spreading to the larynx: an unusual condition.

ABSTRACT

A man in his mid-70s, heavy smoker with chronic alcohol consumption and a chronic exposure to insecticides and burning of crop residues was referred to the surgical oncology department because of a 4-month onset of hoarseness, dyspnoea and laryngeal stridor. He had a history of left nephrectomy due to Fuhrman IV clear cell renal cancer 2 years ago. The patient underwent a bronchoscopy which identified a deforming tumour of the left vallecula, occlusion of 90% of the lumen and did not allow a safe biopsy. Following discussion between the oncological team, total laryngectomy and bilateral neck dissection of levels II, III, IV and V were performed, finding a transglottic tumour of approximately 4×3 cm with extension to the right anterolateral thyroid cartilage. The pathology report described metastatic RCC. The patient recovered well postoperatively and started systemic therapy with a vascular endothelial growth factor receptors inhibitor.
