Voluminous Pheochromocytoma suspected of malignancy: a difficult diagnosis and an uncertain prognosis. About a case

We present a case of voluminous pheochromocytoma in a 53-year-old female patient, suspect of malignancy in the pathologic examination, while emphasizing the importance of the clinical and radiological long-term monitoring.
