Secondary neoplasms of the larynx from a colonic adenocarcinoma

Secondary neoplasms of the larynx are rare and account for 0.09-0,4% of all laryngeal tumours. Cutaneous melanomas are the preponderant primaries metastasizing to the larynx, followed by renal cell carcinomas, breast and lung carcinomas. Colonic adenocarcinoma metastases to the larynx are extremely rare. Tumours spreading to the larynx may be asymptomatic or may result in hoarseness, stridor or airway obstruction. Patients with metastasis of colonic adenocarcinoma to the larynx usually present with disseminated disease. We present a case of an isolated laryngeal metastasis from a colonic adenocarcinoma. The patient was treated with endoscopic surgery and radiation.
