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.

What size of pheochromocytoma is malignant?

The size of pheochromocytomas and the benign or malignant nature of the tumor are not greatly related. Usually, most are familial pheochromocytomas, which are most commonly bilateral, but they have a relatively high recurrence rate and are difficult to treat with fewer available treatment options. Once a pheochromocytoma is detected, it should be taken seriously and treated promptly. The presence of a tumor often indicates that it has developed to the mid and late stages, where it becomes relatively difficult to cure. Regardless of whether the tumor is large or small, it must be taken seriously and treated with care, otherwise, it may easily worsen and affect health.

What department should I go to for pheochromocytoma?

Pheochromocytoma generally requires consultation at the endocrinology or surgical department. Please ask a physician to assess the current situation. For further examination and diagnosis of pheochromocytoma, qualitative and locational diagnostics are necessary. Qualitative diagnostics typically involve blood tests where levels of catecholamine metabolites in the blood and urine are tested to assist in diagnosis; locational diagnostics involve using CT scans, MRI, and ultrasound to help determine the specific location of the tumor. Treatment for pheochromocytoma generally involves surgical removal of the tumor once it is found, combined with medication treatment, which often leads to satisfactory therapeutic outcomes.

The manifestations of pheochromocytoma crisis

For patients with pheochromocytoma, during a crisis, it generally manifests as a sudden increase in the patient's blood pressure, which can rise to above 200-300 mmHg. Additionally, the patient experiences severe headaches and dizziness, severe nausea and vomiting. Some patients may experience significant discomfort and tachycardia, arrhythmias. Some patients also suffer from abdominal or chest pain, labored breathing, and difficulty breathing, and even blurred vision. In severe cases, the excessively high blood pressure can lead to hypertensive cerebral hemorrhage or other unexpected cardiovascular and cerebrovascular diseases. The patient’s vital signs are extremely unstable, often accompanied by multiple organ dysfunction or failure.

Pheochromocytoma clinical manifestations

Pheochromocytoma typically presents with severe hypertension, with blood pressure even reaching above 200/140 mmHg, accompanied by significant discomfort, such as profuse sweating, chest pain, obvious difficulty in breathing, chest tightness, shortness of breath, and other clinical manifestations. Moreover, if not treated timely and effectively, it can even lead to a hypertensive crisis. It also poses a severe threat to the patient’s heart, kidneys, liver, and brain tissues. Some patients might develop cerebrovascular diseases due to very high blood pressure, such as hypertensive cerebral hemorrhage, which can threaten the patient's life.

Can pheochromocytoma be cured?

Currently, with the continuous advancement of surgical techniques, pheochromocytomas can be treated promptly and effectively, achieving favorable outcomes. Once a pheochromocytoma is diagnosed and accurately localized, it is advisable to promptly proceed with surgical intervention. Removing the tumor surgically usually results in effective treatment outcomes. Before surgery, imaging studies and biochemical tests are used for the qualitative and locational diagnosis. After the nature and location of the tumor are clearly identified, the success rate of the surgery can also be increased. Pre-operative use of adrenergic receptor blockers can effectively manage the condition, leading to a reduction in blood pressure and lessening the load on the heart, thereby ensuring smooth conduct of the surgery.
