  Multifocal Paraganglioma and Pheochromocytoma Due to Truncated SDHD Mutation

Pheochromocytoma and paraganglioma (PPGLs) are rare autosomal dominant disorders derived from the neural crest chromaffin tissuesof the autonomic nervous system. The succinate dehydrogenase complex subunit D (SDHD) gene has been implicated as one of the pathogenic genes. Although more than 100 SDHD mutations have been reported, the phenotype-genotype association remains unclear. Here we reported a case of a patient who presented with multifocal PPGLs and with a rare SDHD mutation. It is the first report linking this variant to multifocal PPGLs. In addition, we suggest patients with truncated SDHD mutations should undergo whole-body imaging examinations because of multifocality.
