What are the clinical characteristics of hereditary paraganglioma pheochromocytoma?
Clinical characteristics: Hereditary paraganglioma-pheochromocytoma (PGL/PCC) syndromes are characterized by paragangliomas (tumors that arise from neuroendocrine tissues distributed along the paravertebral axis from the base of the skull to the pelvis) and pheochromocytomas (paragangliomas that are confined to the adrenal medulla).
Where are sympathetic extra adrenal paragangliomas usually found?
In contrast, sympathetic extra-adrenal paragangliomas are generally confined to the lower mediastinum, abdomen, and pelvis, and are typically secretory. Pheochromocytomas, which arise from the adrenal medulla, typically lead to catecholamine excess.
Can a proband have hereditary PGL / PCC syndrome?
A proband with a hereditary PGL/PCC syndrome may have inherited the pathogenic variant from a parent or, rarely, have a de novo pathogenic variant; the proportion of individuals with a de novo pathogenic variant is unknown.
