Adrenocortical carcinoma (ACC) is an uncommon malignancy originating from cortex of adrenal gland. The most common pitfall in diagnosis of ACC is to distinguish it from pheochromocytoma. Here we report a 62-year-old hypertensive man with presentation of dyspnea. The laboratory data showed an increase in urine cortisol and renin with a mild increase in aldosterone, but decrease in adrenocorticot...

Cardiovascular and plasma catecholamine responses to metoclopramide (MCP), a dopamine antagonist, were examined in 5 patients with pheochromocytoma, 12 patients with essential hypertension (EHT) and 9 normotensive (NT) subjects who displayed symptoms suggestive of pheochromocytoma on a constant daily intake of 100 mEq sodium and 80 mEq potassium. Significant pressor responses to intravenous dos...

This review provides current understanding of the pathophysiology of pheochromocytoma and the wide range of associated clinical manifestations that have led to earlier recognition of the disease. In addition, it reviews optimal screening methods and localization techniques that have enhanced the clinician's ability to make the diagnosis with greater certainty. This article will also discuss alt...

Metastatic pheochromocytoma in the spine is rare, and there is no standard curative management. Treatment via open surgery is often risky in the perioperative period, while osteoplasty by cement augmentation is a less invasive option.We describe 2 patients with recurrence of pheochromocytoma involving the spine and the pelvis who were successfully treated with osteoplasty by cement augmentation...

Ectopic secretion of adrenocorticotropic hormone (ACTH) is an infrequent cause of Cushing's syndrome. We report a case of ectopic ACTH syndrome caused by a pheochromocytoma. A 53-year-old female with clinical features of Cushing s syndrome presented with serious recurrent hypertensive crisis. Endocrinological investigation confirmed the diagnosis of ectopic ACTH production and revealed markedly...

BACKGROUND This study aims to introduce the diagnosis and surgical treatment of the rare disease multiple endocrine neoplasia type 2A (MEN 2A). METHODS Thirteen cases of MEN 2A were diagnosed as medullary thyroid carcinoma (MTC) and pheochromocytoma by biochemical tests and imaging examination. They were treated by bilateral adrenal tumor excision or laparoscopic surgery. RESULTS Nine patie...

Background: Investigation of the maternal cause death and pregnancy-related is one most important responsibilities a forensic pathologist. From public health point view, it may help to prevent losses during following pregnancy save lives women, especially in developing countries. Methods: We report case with history neurofibromatosis type 1 who presented asymptomatic normotensive normal laborat...

A pheochromocytoma was maintained in rats from the New England Deaconess Hospital by giving the rats s.c. injections of isolated tumor cells. The animals were sac rificed 3 to 4 weeks after transplantation, the tumors were excised, and purified tumor cells were prepared. Cyclic nucleotide phosphodiesterase of the purified tumor cells was characterized and compared with that of the adrenal medul...

This Hypertension Grand Rounds shows how applying new clinical laboratory techniques helped to diagnose pheochromocytoma in a difficult case. In the setting of long-standing, sustained hypertension, the patient had a hypertensive paroxysm during anesthesia induction for surgery, leading to suspicion of a pheochromocytoma. Conventional testing, including CT scanning and fractionated urinary meta...

UNLABELLED Although (123)I-MIBG has been in clinical use for the imaging of pheochromocytoma for many years, a large multicenter evaluation of this agent has never been performed. The present study was designed to provide a prospective confirmation of the performance of (123)I-MIBG scintigraphy for the evaluation of patients with known or suspected primary or metastatic pheochromocytoma or para...
