title: Granular cell myoblastoma of the supraglottis.
abstract: Granular cell myoblastoma is an unusual benign tumour, which, when occurring in the larynx usually affects the vocal cords and causes hoarseness. We present a case presenting with symptoms strongly suggestive of globus pharyngis. These tumours probably arise from neuroectodermal tissue, and the current nomenclature is a misnomer. Complete excision rather than biopsy is recommended, as biopsy material may be misinterpreted as squamous carcinoma. In this case, endoscopic removal of the tumour was successful in producing complete symptomatic relief.
