For pheochromocytoma, the term usually refers to tumors arising from the chromaffin tissue of the neural crest. Clinically, the main typical symptoms include severe hypertension, along with nausea, vomiting, intense headache, and dizziness. Additionally, it may also cause the patient to be in a continuous high metabolic state, characterized by persistent hyperglycemia, nausea, vomiting, and excessive sweating. If not treated promptly and effectively, it may pose serious threats to the patient's heart, brain, and kidneys. In severe cases, it could even be life-threatening. Surgery is commonly recommended for treatment.
