3-methoxytyramine has been researched along with Pheochromocytoma in 35 studies
3-methoxytyramine: RN given refers to parent cpd
3-methoxytyramine : A monomethoxybenzene that is dopamine in which the hydroxy group at position 3 is replaced by a methoxy group. It is a metabolite of the neurotransmitter dopamine and considered a potential biomarker of pheochromocytomas and paragangliomas.
Pheochromocytoma: A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.
