PGL3 syndrome is caused by mutations in SDHC gene. At present only few families affected by SDHC mutations have been reported in the literature and in each of them the clinical presentation was characterized by paragangliomas located only in the head and neck region.No evidence of thoracic or abdominal catecholamine secreting chromaffin tumours has been reported so far. Here we report the case of a 15 yr old hypertensive female affected by a norepinephrine-secreting abdominal paragangliomas who was found to harbour a novel nonsense SDHC mutation, demonstrating that the clinical presentation of PGL3 syndrome can be wider than expected.
