Pheochromocytoma is a rare tumor that affects the adrenal glands and produces an excessive amount of catecholamines, hormones that regulate heart rate, blood pressure, and other functions. This excessive hormone production can cause symptoms such as high blood pressure, headache, sweating, and rapid heartbeat. Pheochromocytoma is usually diagnosed through blood tests, urine tests, and imaging studies.

Treatment typically involves surgical removal of the tumor, followed by medications to manage blood pressure and regulate hormone levels. In some cases, pheochromocytoma may recur or spread to other parts of the body, so close monitoring is important for patients with this condition. Early diagnosis and prompt treatment are crucial for managing pheochromocytoma and reducing the risk of complications.
