title: Isolated laryngeal amyloidosis in a patient with a hoarse voice.
abstract: We present a case of a 59-year-old woman with a hoarse voice of 3 weeks duration. A polypoid lesion involving the anterior aspect of the left vocal cord was detected by flexible fibreoptic endoscopic examination. Flexible bronchoscopic examination was unremarkable. Microlaryngoscopy and excisional biopsy of the laryngeal lesion were carried out. Histology of the biopsy showed stroma exhibiting birefringence under polarised light and a diagnosis of laryngotracheal amyloidosis was made. Systemic amyloidosis was ruled out by further investigations including positron emission tomography scan. Her hoarse voice improved following the excisional biopsy and regular follow-up was arranged for early diagnosis of recurrence.
