Amyloidosis is a heterogeneous family of disorders associated with extracellular proteinaceous deposits with characteristic microscopic, histochemical, and ultrastructural features. It usually presents as nodular or polypoid lesions and can be located in any part of the body, including the larynx or trachea. OBJECTIVE: To present a case of laryngeal amyloidosis and diagnosis amyloid in the larynx based on the patient's history and the finding of apple-green birefringence with polarized light after staining with Congo red. CASE REPORT: An adult woman had a history of hoarseness lasting for 6 years and was having difficulty breathing. Larynogoscopy revealed a glottic mass on the right side, which was surgically removed. Histopathological diagnosis revealed amyloidosis. The primary treatment of laryngeal amyloidosis has been endoscopic excision of the mass with laser CO2. However, for a large mass, the glottic view is facilitated by direct surgical visualization of the larynx. CONCLUSION: Slowly evolving laryngeal masses may be due to laryngeal amyloidosis, which should be considered in the differential diagnosis of benign tumors of the larynx.
