[Bilateral adrenal pheochromocytomas in von Hippel-Lindau disease].

The pheochromocytoma is a medullo-adrenal tumor which develops at the cost of the chromaffin cells. It appears in 11-19% of cases of von Hippel-Lindau's disease (VHL), is often bilateral, and the symptomatology is often crude: arterial hypertension is frequently isolated and unstable, and the classic triad of headache, palpitations and sweating is quite rarely observed. We report four observations of bilateral pheochromocytomas in patients with von Hippel-Lindau's disease (three with phenotype IIA and one with phenotype IIB). The tumor was bilateral during the diagnosis in three cases; in the fourth patient, the attack on the contralateral adrenal gland came two years after the first adrenalectomy. All the patients had undergone an adrenalectomy by open surgery after a short preparation of 48 hours; replacement therapy was begun in each patient. Morbidity was low, and the patients submitted to a prolonged follow-up in order to screen for the onset of future lesions of VHL.
