Resumen

La existencia de afectación metastásica de la laringe es rara. Se han descrito unos 150 casos en la literatura. En tan sólo 8 casos, el tumor primario se trataba de un adenocarcinoma de colon. Presentamos el caso de una paciente de 80 años, con antecedente de adenocarcinoma coloide de colon tratado 7 años antes, remitida por disnea crónica y progresiva. En la exploración presentaba una masa esférica subglótica causante de un importante compromiso de espacio de la vía respiratoria. En el estudio radiológico reveló la existencia de una masa tiroidea. La paciente fue tratada mediante traqueotomía, resección de masa subglótica, cuya biopsia intraoperatoria fue de "tumor mucrosecretor", y tiroidectomía total. El diagnóstico definitivo de la masa subglótica fue de metástasis de un adenocarcinoma coloide de colon. En la revisión de la literatura realizada, no existe ningún caso previamente descrito de metástasis laríngea de un adenocarcinoma coloide de colon. Discutimos el diagnóstico anatomopatológico, clínico y radiológico, así como las posibles opciones terapéuticas de las neoplasias secundarias de laringe.

Abstract

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.
