Is a tumour that usually originates from the adrenal glands’ chromaffin cells, causing overproduction of catecholamines, powerful hormones that induce high blood pressure and other symptoms.
A rare tumor that most frequently occurs in the adrenal gland but may occur elsewhere; it usually secretes epinephrine and norepinephrine, which cause many signs and symptoms, including hypertension.
A tumor of the adrenal medulla chromaffin cell characterized by hypersecretion of epinephrine with intermittant to permanent hypertension. Death can occur if not recognized and the tumor removed.
Tumor of the adrenal gland that causes hypersecretion of epinephrine and norepinephrine, resulting in intermittent hypertension and symptoms of headache, palpitations, sweating, and nervousness. Treatment is usually surgical removal of the tumor.
A tumor of functional chromaffin cells of the adrenal medulla that produces excess catecholamines, causing hypertension, nausea, headache, anxiety, and dyspnea.
A tumor of the adrenal gland that causes the release of excessive amounts of the adrenal hormones epinephrine and norepinephrine. One or more pheochromocytomas may develop, usually in the adrenal medulla (the inner layer of the adrenal glands). Pheochromocytomas may also develop outside the adrenal glands, usually in the abdomen. The tumors occur with equal frequency in men and women. Only about lo percent of them are cancerous.
A small vascular tumor of the inner region (medulla) of the adrenal gland. By its uncontrolled and irregular secretion of the hormones epinephrine and norepinephrine, the tumor causes attacks of raised blood pressure, increased heart rate, palpitations, and headache.
A tumor derived from neural crest cells of the sympathetic nervous system that is responsible for about 0.1% to 2% of all cases of hypertension. The tumor releases catecholamines (e.g., norepinephrine and epinephrine), which cause episodic or sustained signs and symptoms (e.g., palpitations, sweating, headaches, fainting spells, tremor, nausea, dyspepsia, pallor, chest or abdominal pain, hyperglycemia, weakness, anxiety or feelings of impending doom, and hypertensive emergencies). It may result from an inherited autosomal dominant trait. All races and both sexes are affected, with symptoms most commonly beginning between ages 30 and 40.
A growth that develops from the chromaffin cells in the adrenal gland, leading to excessive production of catecholamines, potent hormones responsible for inducing elevated blood pressure and various other symptoms.
An adrenal gland tumor arises from the chromaffin cells, resulting in the excessive secretion of catecholamines. These potent hormones contribute to the manifestation of high blood pressure and various accompanying symptoms.
A tumor that originates in the adrenal gland can lead to a condition called hyperadrenalinism, where there’s an overproduction of adrenaline. This condition presents with sudden episodes of high blood pressure, chest discomfort, paleness, sweating, feeling sick, throwing up, severe headaches, cold and sometimes bluish hands, trembling, leg muscle cramps, pupil constriction, fever, anxiety, and an intense fear of dying. These episodes can happen unexpectedly and at varying times. They can last anywhere between five to thirty minutes, leaving the individual feeling completely drained. Recovery from these episodes can take anywhere from hours to days. The recommended treatment is to surgically remove the tumor. This condition is also known as paraganglioma.
