A case of recurrence and metastasis of pheochromocytoma: a case report.

Pheochromocytomas are rare tumors that develop from chromaffin cells of the adrenal medulla or from extra-adrenal paraganglia . These tumors frequently produce catecholamines, and excessive secretion can lead to a variety of symptoms, including episodic hypertension and metabolic disorders. Such complications can significantly impact cardiovascular health as well as kidney and vascular function, and there is notable concern regarding recurrence and metastasis following surgical resection. This article analyzes the case characteristics, diagnosis, and treatment of a patient with pheochromocytoma who experienced relapse after surgical resection, thereby providing a reference for clinical practice.
