title: Teflonomas of the larynx and neck.
abstract: Intracordal fluorocarbon (Teflon, Mentor O and O Inc, Norwell, MA) injection has been used for decades to correct paralytic dysphonia, a result of unilateral laryngeal paralysis. Infrequently, the Teflon extravasates and infiltrates into the soft tissues of the neck and larynx producing a mass that clinically simulates a malignant lesion. We report eight cases of so-called "Telonomas" of the larynx and neck that have been identified in the files of the Armed Forces Institute of Pathology Otolaryngic Tumor Registry and from the Cytopathology Service at the George Washington University Medical Center. Patients ranged in age from 31 to 72 years. Vocal cord paralysis, treated by Teflon injection, was caused by primary laryngeal carcinoma or metastatic carcinoma (breast, lung) involving the recurrent laryngeal nerve, surgical trauma to the recurrent laryngeal nerve, or postviral neuritis. Subsequent symptomatology, related to extravasation of the Teflon with a resulting "Teflonoma", included a neck mass or persistent hoarseness. Infrequently, there was associated airway obstruction or voice changes. Diagnosis was made by fine needle aspiration or by excision of the suspicious mass and subsequent identification of a foreign body granulomatous reaction with associated birefringent material. Infrared absorption spectrophotometry identified the foreign material as a fluorocarbon which was further substantiated by scanning electron microscopy and energy dispersive x-ray analysis. Surgical removal of the mass alleviated all symptoms.
