Abstract:
Paragangliomas of the larynx (LPG) are unusual neuroendocrine tumors 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, radiologic, and surgical features of a supraglottic LPG seen in a 40-year-old woman with a 8-month history of slowly progressive hoarseness. The tumor 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.
