[Laryngeal metastasis from colloid adenocarcinoma of the colon: report of a case].
Metastatic involvement of the laryngeal is very rare, with around 150 cases reported to the literature. In eight of these cases, the primary tumor was a colon adenocarcinoma. We report the case of a 80 year-old woman treated of a colloid adenocarcinoma of 7 years earlier, referred to us for chronic and progressive dyspnea. Endoscopic examination showed a subglottic spherical mass, which caused an important compromise of the respiratory airway. Tomographic studies revealed also a thyroid mass. The patient was treated with a tracheostomy, resection of the subglottic mass (with intraoperative diagnosis of "mucin producing tumor"), and total thyroidectomy. The final pathologic diagnosis of the subglottic mass was a metastasis of colloid adenocarcinoma of the colon. In the literature reviewed there are no previous reports of metastatic involvement of the larynx with this type of colon adenocarcinoma. We discuss the clinical and radiological findings, and therapeutic options for metastasis to the larynx, as well as pathological differential diagnosis.
