Abstract

Background/objectives

Laryngeal paragangliomas are benign slow growing tumors with symptoms resembling squamous cell carcinoma. Hoarseness or dysphasia is the commonest presenting symptom and usually it presents as a submucosal mass on laryngoscopy. A total of 90% of these tumors occur in the supraglottic larynx and the rest in the glottis and the subglottic region. Functional activity is seen in a few (2.9%), none are associated with paraneoplastic syndromes.

Setting

Department of Head and Neck Oncosurgery, Kidwai Memorial Institute of Oncology, Bengaluru.

Case report

A 35-year-old male presented to us with hoarseness of voice since 4 months duration. Contrast arteriography demonstrated that the left superior thyroid artery supplied greater than 80% of the blood supply to the laryngeal mass. Superselective embolization was done from the right femoral under local anesthesia and sedation which was uneventful.

Intervention

The tumor was excised from lateral pharyngotomy approach with an elective tracheostomy. Microscopy suggested it to be paraganglioma and immunohistochemistry confirmed it.

Conclusion

Complete surgical resection or partial laryngectomy with meticulous dissection of surrounding tissues and preservation of neurovascular structures give an excellent prognosis as far as oncological clearance is concerned. Malignant paragangliomas of the larynx are rare and a major meta-analysis is necessary to provide a true biological behavior of this tumor.
