Recurrent benign adrenal pheochromocytomas associated with hemihypertrophy
UNLABELLED We report a case of a female with hemihypertrophy, who developed five recurrences of pheochromocytomas until the age of 35. Timely follow-up of the patient's blood pressure assisted in early diagnosis and treatment of recurrent tumors. LEARNING POINTS Recurrent benign pheochromocytomas should raise suspicion of a genetic syndrome.A pheochromocytoma at a young age has a high propens...
متن کاملClinical and Pathological Characteristics of Hypertensive and Normotensive Adrenal Pheochromocytomas.
INTRODUCTION Pheochromocytoma/Paraganglioma (PPGL) present with an extremely variable clinical picture which ranges from dramatic, to mild, to silent, depending on tumor attitude to release catecholamines. Hypertension is the hallmark of these tumors but is not always present. Distinct differences of clinical manifestations exist in hypertensive pheochromocytomas (HPs) and normotensive pheochro...

متن کاملExpression of mRNA coding for four catecholamine-synthesizing enzymes in human adrenal pheochromocytomas.
OBJECTIVE To understand the molecular mechanisms by which catecholamine synthesis is controlled in pheochromocytomas--tumors that synthesize and release catecholamines, which are related to various clinical manifestations of the condition. METHODS We measured the concentrations of mRNA coding for the catecholamine-synthesizing enzymes tyrosine hydroxylase, aromatic L-amino acid decarboxylase ...
متن کاملStudy of Microvessel Density and the Expression of Vascular Endothelial Growth Factors in Adrenal Gland Pheochromocytomas
Angiogenesis (neoangiogenesis), a process of neovascularization, is an essential step for local tumor growth and distant metastasis formation. We have analysed angiogenesis status: vascular architecture, microvessel density, and vascular endothelial growth factors expression in 62 adrenal pheochromocytomas: 57 benign and 5 malignant. Immunohistochemical evaluation revealed that vascular archite...
