Introduction: Cushing’s syndrome results from increased or aberrant expression of ACTH, CHR, or neuroendocrine receptors that leads to uncontrolled hypersecretion of cortisol. The most common cause is ACTH-secreting pituitary adenomas. Alternatively, the glucocorticoid excess may be due to adrenal neoplasia or to ectopic ACTH – secreting tumors. There are rare reports of patients with a meningioma secreting CRH presenting paraneoplasic Cushing’s syndrome.<p ...

Graves’ disease is characterized by the occurrence of antibodies against thyroid-stimulating hormone (TSH) receptor that stimulate the gland to produce T4 and T3. It can be accompanied by an infiltrative orbitopathy and oftalmopathy. Another seldom- regognized feature of this disease is thymic hyperplasia.The authors report the case of a 22-year-old woman with Graves’ disease (TSH receptor antibodies 178 U/l) with exuberant oftalmopathy and an ...

Pheocromocytoma is a catecholamine-secreting tumor that arises from chromaffin cells of the adrenal medulla. In general, they are unilateral and the treatment of choise is complete surgical resection. Surgery and other medical procedures such as chemotherapy or radiotherapy may result in massive catecholamine release that can be fatal. Some form of preoperative pharmacologic preparation is indicated for all patients to control blood pressure, arrhytmia and promote intravascula...
