[Non-chromaffin laryngeal paraganglioma. Clinical and electron microscopical study]

The authors describe the case of a 51 year-old woman presenting with a very large laryngeal paraganglioma in the aryepiglottic fold which had passed through the cricothyroid membrane and invaled the thyroid. A crico-hyoido-pexy enabled the tumour to by completely removed and anatomo-pathological examination showed degeneration. Under electron microscopy, the ultrastructure of the tumour was similar to that of chromaffin paragangliomas. It is three years since this patient was cured.
