The difference between pheochromocytoma and adrenal tumor is that pheochromocytoma is a type of adrenal tumor.
Pheochromocytomas are tumors that originate in chromophilic tissue in the adrenal medulla, sympathetic ganglia, or elsewhere. Because the tumor may release large amounts of catecholamines intermittently or persistently, patients clinically present with paroxysmal or persistent hypertension and multiple organ dysfunction and metabolic disorder syndromes.
Adrenal glands are important endocrine glands in the body, consisting of the cortex, medulla, and stroma, which can lead to adrenal tumors due to heredity, endocrine changes, and environmental factors. Adrenal tumors can be non-functional or functional, the symptoms of the former are usually more insidious, while functional adrenal tumors may appear due to abnormal secretion of cortisol, aldosterone, catecholamines and sex hormones.
Pheochromocytoma is one of the adrenal tumors in the classification of adrenal medullary tumors and extra-adrenal paragangliomas.
Clinical manifestations and endocrine indicators of adrenal tumors are diverse, and doctors will combine the patient’s pathology, clinical manifestations, laboratory tests and imaging diagnosis to confirm the diagnosis.
If you feel unwell, it is recommended to go to the hospital in time to avoid delaying the condition or causing adverse reactions.
