Article information

Paragangliomas of the larynx (LPG) are unusual neuroendocrine tumours that are seen as a vascular submucosal mass, with a female predilection. We add another case of LPG to the 77 previously reported in the literature. We present the clinical, radiological, and surgical features of a supraglottic LPG seen in a 40-year-old woman with an 8-month history of slowly progressive hoarseness. The tumour was removed approaching a lateral thyrotomy. The patient remains disease free 18 months after surgery. Preoperative CT, angiography, and embolization are useful in making the diagnosis and reducing perisurgical bleeding of LPG before surgical intervention. Complete excision through an external mucosa-sparing approach is the treatment of choice.

Los paragangliomas laríngeos (PGL) son tumores poco frecuentes, derivados del sistema neuroendocrino, que suelen iniciarse como una masa submucosa endolaríngea, con predilección por el sexo femenino. Aportamos un nuevo caso a los 77 publicados. Presentamos las características clínicas, radiológicas y quirúrgicas de un PGL supraglótico de una mujer de 40 años de edad, con clínica de 8 meses de evolución de ronquera. El tumor fue resecado mediante tirotomía lateral, previa embolización selectiva. La paciente permanece libre de enfermedad después de 18 meses tras la cirugía. La tomografía computarizada, la angiografía y la embolización preoperatorias son útiles en el diagnóstico y en la reducción del sangrado periquirúrgico. La exéresis completa vía externa con conservación mucosa es el tratamiento de elección.
