Patients with infrequent and mild paroxysms; Patients with frequent or severe paroxysms It has previously been estimated that approximately 10%-15% of pheochromocytomas are due to hereditary causes. FOIA However, several areas are the subject of debate, including the identification of malignant potential, the diagnosis of medullary hyperplasia, and the recognition of composite tumors. These studies indicate that the frequency of germline mutations associated with isolated pheochromocytoma is higher than previously estimated, with both hospital-based series and a large population-based series indicating that the frequency of germline mutations in RET, VHL, SDHB, and SDHD taken together approximates 20%.

Identification of patients with hereditary pheochromocytoma is important because it can guide medical management in mutation-positive patients and their families. The majority of tumors originate in the adrenal medulla, but they may also arise from sympathetic ganglia (also referred to as paraganglioma). trailer Hypertension, either sustained or paroxysmal, is the clinical hallmark of pheochromocytoma and is commonly attributed to catecholamine excess.

The most common presenting symptoms are hypertension (including labile hypertension), palpitations, increased sweating, severe headache, tremors, pallor, and dyspnea. However, our increased understanding of the three hereditary syndromes (neurofibromatosis 1, multiple endocrine neoplasia type 2, and von Hippel-Lindau syndrome) in which pheochromocytoma is found and the recent discovery that mutations in genes in the succinate dehydrogenase family (SDHB and SDHD) predispose to pheochromocytoma have necessitated a re-evaluation of the genetic basis of pheochromocytoma.
