A right adrenal tumor was found incidentally by renal echography in a 
25-year-old man, who had been on hemodialysis for 4 years. Inquiry and clinical 
examination suggested pheochromocytoma, which was confirmed by plasma 
catecholamine measurements. Subsequent adrenalectomy was uneventful. Although 
hypertension, headache, and diaphoresis are common symptoms in a dialyzed 
patient, pheochromocytoma has to be eliminated in the presence of this clinical 
triad.
