Management of laryngeal amyloidosis--the experience of Taipei Veterans General Hospital.
Laryngeal amyloidosis is an uncommon disease accounting for 0.68% of benign tumors of the larynx. It can present as a nodular tumor or diffuse subepithelial deposition forming a bulging mass and causing hoarseness, dysphagia or even airway obstruction. We present our experience in the management of laryngeal amyloidosis, and discuss the clinical features and histopathological characteristics of the disease. Reports on benign laryngeal tumor from June 1988 to June 1998 at Taipei VGH were searched to identify and collect amyloid cases for chart review. Five cases of laryngeal amyloidosis were found in the records. The sites of involvement were false cord, ventricle, post-cricoid, and arytenoid-epiglottic fold. No evidence of systemic amyloidosis involvement was observed for any of the five cases. All cases were treated with CO2 laser excision. Recurrence occurred in two patients within one year. More extensive CO2 laser excision was subsequently performed, with no more recurrences noted as of the last follow-ups. Laryngeal amyloidosis is a benign disease; however, surgical management is required when it is symptomatic. Recurrences or large-sized tumors may be a problem; however, advances in laser technology and the cumulative experience of treating benign lesions of the larynx have made CO2 laser endoscopic excision an effective treatment option.
