title: Granular cell tumour of the larynx.
abstract: A granular cell tumour may present as clinically innocuous lesions on the vocal cords and the diagnosis is usually made by histopathology. However, the granular cells characteristic of this tumour may not be obvious and accompanying epithelial hyperplasia may be interpreted by the pathologist as invasive squamous cell carcinoma. Good communication between pathologist and surgeon is required to ensure that clinically benign lesions on the vocal cords are not misdiagnosed. The diagnosis of granular cell tumour can be confirmed by immunocytochemical staining for S100 antigen.
