A CASE OF PHEOCHROMOCYTOMA OF THE URINARY-BLADDER IN A LONG-TERM HEMODIALYSIS PATIENT

The development is reported of a pheochromocytoma of the urinary bladd er in a 33-year-old patient with systemic lupus erythematosus who had undergone long-term hemodialysis. A hypertensive episode followed by d efecation was demonstrated by the monitoring of blood pressure with a portable automated sphygmomanometer without elevation of plasma catech olamines. The tumor was surgically removed and normalization of the pa tient's blood pressure followed. Thus, monitoring of blood pressure fo r 24 h proved useful for the diagnosis of pheochromocytoma and, in par ticular, of paroxysmal hypertension.
