Pheochromocytoma during pregnancy is extremely rare. Its clinical manifestation includes hypertension with various clinical presentations, possibly resembling those of pregnancy-induced hypertension. The real challenge for clinicians is differentiating pheochromocytoma from other causes of hypertension (preeclampsia, gestational hypertension, and pre-existing or essential hypertension), from ot...

We report a case of elderly Chinese lady with neurofibromatosis type-1 presenting with longstanding palpitation, paroxysmal hypertension and osteoporosis. Biochemical testing showed mild hypercalcaemia with non-suppressed parathyroid hormone level suggestive of primary hyperparathyroidism, and mildly elevated urinary fractionated normetanephrine and plasma-free normetanephrine pointing to a cat...

INTRODUCTION Retinoic acid is a regulator of gene expression which, by binding to its nuclear receptor, determines the degree of differentiation in multiple cancer cell types. On the basis of this capability it was introduced, e.g. in the therapy of neuroblastoma. In cells derived from neural crest, such as neuroblastoma cells, retinoic acid initiates differentiation into neurons. This substanc...

BACKGROUND Neurofibromatosis type 1 is an autosomal dominant condition that has a variety of clinical manifestations. Essential or secondary hypertension may be associated with neurofibromatosis. A rare finding is hypertension due to pheochromocytoma in patient with neurofibromatosis type 1. CASE REPORT We present a case with a 7-year medical history of hypertension which was poorly controlle...

The management of hereditary pheochromocytoma has drastically evolved in the last 20 years. Bilateral pheochromocytoma does not increase mortality in MEN2 or von Hippel-Lindau (VHL) mutation carriers who are followed regularly, but these mutations induce major morbidities if total bilateral adrenalectomy is performed. Cortical sparing adrenal surgery may be proposed to avoid definitive adrenal ...

Background: Bilateral adrenal tumors are not common in clinical practice, but are an important source of ectopic adrenocorticotropic hormone (ACTH) secretion. Standard operative management for bilateral pheochromocytomas might dictate the removal of the involved adrenal gland and the removal of the contralateral adrenal gland. We present a case of bilateral ACTH-secreting pheochromocytoma treat...

INTRODUCTION Pheochromocytoma is a rare cause of hypertension but it could have severe consequences if not recognized and treated appropriately. The association of pheochromocytoma and thrombosis is even rarer but significantly increases management complexity, morbidity and mortality. To the best of our knowledge, this is the first report of a patient with pheochromocytoma presenting with left ...

some of the endocrinologic diseases, especially acromegaly, cushing and pheochromocytoma have multiple effects on blood glucose metabolism and regulation in non-diabetic patients. in this retrospective survey, records of patients of tehran medical sciences university hospitals have been reviewd. of 124 acromegals, gtt was performed for 51 patients, being impaired in 18%. to evaluate diabetes, f...

Introduction. Ghrelin, originally isolated from the endocrine cells of gastric mucosa, is also expressed in many peripheral tissues, including normal adrenals and adrenocortical tumors. It was shown that ghrelin stimulates proliferation inhibits apoptosis cells. In current study, we compared expression at protein level various adrenal We analyzed whether immunoreactive could be considered as a ...
