A novel mutation identified in a patient with pheochromocytoma and renal cell carcinoma [PDF]
Pheochromocytomas might be sporadic or genetic. Genetic pheochromocytoma is associated with multiple endocrine neoplasia (MEN) type 2A, MEN type 2B, and von Hippel-Lindau (VHL) disease. RET mutations are identified in more than 90% of index cases of MEN2

Risk of metastatic disease in the cluster 2-related pheochromocytoma/paraganglioma (PPGL) is low. In MEN2 patients, identification of origin of met astases from pheochromocytoma (PCC) or medullary thyroid carcinoma (MTC) is challenging as both are of ...

Role of VEGF-A and Its Receptors in Sporadic and MEN2-Associated Pheochromocytoma [PDF]
Pheochromocytoma (PHEO), a rare catecholamine producing tumor arising from the chromaffin cells, may occurs sporadically (76%–80%) or as part of inherited syndromes (20%–24%). Angiogenesis is a fundamental step in tumor proliferation and vascular endothelial growth factor (VEGF-A) is the most well-characterized angiogenic factor. The role of angiogenic

Management of hyperparathyroidism (PHP) in MEN2 syndromes in Europe [PDF]
Hyperparathyroidism occurs in 20-30% of MEN2A syndrome patients. It is usually associated with mild disease and is frequently asymptomatic, especially in younger age. There is genotype/phenotype association and PHP is usually associated with codon 634 mutations; however association with more "rare" mutations has also been reported. The pathology of the

ABSTRACT Introduction Thyroid nodules are less common but more often malignant in pediatric patients than in adults. Our objectives were to study the features of benign vs. malignant thyroid nodules in a large pediatric patient cohort. Methods Retrospective observational cohort study. Consecutive patients aged 0.01–17.9 years at evaluation between 1997–

Diagnosis of pheochromocytoma with special emphasis on MEN2 syndrome
Pheochromocytomas/paragangliomas(PHEOs/PGLs) are rare but treacherous catecholamine-producing tumors which, if overlooked or improperly treated, will almost invariably prove fatal. Patients with MEN2 PHEOs have a high incidence of paroxysmal attacks and a higher prevalence of hypertension and other cardiovascular problems than do patients with Von ...
