We report the case of an extra-adrenal pheochromocytoma discovered in the setting of an abdominal mass. Observation: The patient was 25-year-old and presented with headaches, excessive sweating and palpitations, followed by a sensation of abdominal weightlessness and diastolic arterial hypertension. Abdominal computed tomography revealed a retroperitoneal, right para-renal extra-adrenal mass. In biology, an increase in urinary methoxylated derivatives at the expense of normetanephrine. Conclusion: Pheochromocytoma is a rare disease, diagnosed by measuring urinary or plasma methoxylated derivatives. Conventional or nuclear imaging allows topographic diagnosis. Genetic studies helps to identify other tumors. %K Pheochromocytoma %K Arterial Hypertension %K Methoxylated Derivatives %K Genetics %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=127027
