Abstract

Objective:

To report a rare case of a laryngeal paraganglioma related to succinate dehydrogenase gene mutation C.

Method:

A case report and a review of the world literature concerning succinate dehydrogenase mutations and laryngeal paraganglioma are presented.

Results:

We identified a laryngeal paraganglioma in a 38-year-old woman, related to a very rare, deleterious in exon 4 of the succinate dehydrogenase mutation C. This mutation was a non-sense mutation: c.183G >A leading to p.Trp61X. No other neuroendocrine tumour was identified in this case, but a thyroid papillary carcinoma was concomitantly discovered and cured.

Conclusion:

To our knowledge, this is the first report in the world literature of laryngeal paraganglioma related to a succinate dehydrogenase mutation C. The case presented underlines the fact that every patient with paraganglioma should be tested for succinate dehydrogenase genetic mutations, even if a family history of paraganglioma is absent, in order to enable appropriate clinical management and to improve our knowledge of familial paraganglioma.
