A case of metastatic colon adenocarcinoma in the larynx.

Metastatic carcinomas in the larynx are uncommon, and laryngeal tumors originating from the colon are extremely rare. We report a case of metastatic laryngeal tumor originating from a colon adenocarcinoma in an 81-year-old female. Only a tracheostomy was performed because the patient presented with multiple metastases in other regions. The diagnosis, route of metastasis, treatment and prognosis of metastatic laryngeal tumors are discussed.
