Paragangliomas are rare benign neuroendocrine tumors that originate from the neural crest-derived cells. Paragangliomas in the head and neck are typically found in the region of the carotid body, jugular bulb, and along the 9th and 10th cranial nerves. Laryngeal paragangliomas are rare tumors and are found along the superior laryngeal nerve and recurrent laryngeal nerve. Hoarseness or dysphagia is the most common presenting symptom, and surgical excision is the treatment of choice. A 58-year-old female presented with complaints of progressive difficulty in breathing, especially on lying down with difficulty in swallowing for 1 year. Examination revealed a smooth mass lesion involving the laryngeal aspect of the epiglottis, left pharyngoepiglottic fold, and left aryepiglottic fold. Left endolarynx could not be visualized. Imaging showed a well-defined highly enhancing lesion with multiple feeders from superior thyroid, pharyngeal, and esophageal vasculature. The presumptive diagnosis was a vascular lesion or glomus tumor. The tumor was operated by lateral pharyngotomy approach with a temporary tracheostomy without preoperative embolization. Final histopathology confirmed it to be paraganglioma. The paragangliomas of the larynx are rare neuroendocrine tumors. Complete surgical excision of tumor with preservation of neurovascular structures gives an excellent prognosis.
