[Extra-adrenal pheochromocytoma associated to SDHD gene mutation].

Unlabelled: Hereditary paraganglioma/pheochromocytoma syndrome is an autosomal dominantly inherited disease caused by germline mutation of the genes encoding subunits of the mitochondrial succinate dehydrogenase (SDH) enzyme involved in the mitochondrial respiratory chain. The pathogenetic role of SDH gene mutations was first recognized in 2000. Authors present the history of a patient with extra-adrenal pheochromocytoma who represents in Hungary the first genetically confirmed case of hereditary paraganglioma/pheochromocytoma syndrome due to disease-causing mutation of the SDHD gene.
