Feocromocitoma asociado a enfermedad von Hippel–Lindau

Von Hippel–Lindau (VHL) disease (OMIM: 193300) is a familial cancer syndrome, associated with various benign and malignant tumours, mainly retinal and central nervous system haemangioblastomas, renal cell carcinomas and pheochromocytomas. We describe the case of a 8 years old patient with arterial hypertension, blurred vision and family history of pheochromocytoma. A left adrenal mass is observed in doppler ultrasonography and high levels of normetanephrines in orine. Identification of a mutation in the VHL gen (OMIM: 608537) confirms the diagnosis of VHL disease. The diagnosis should be suspected in patients with early onset of pheochromocytoma, even more if there is a family history of this kind of tumors.
