Although hypertension, sustained or paroxysmal, is usually a cardinal feature of pheochromocytoma, cases in which patients with this disorder were normotensive have been reported. To extend further the clinical spectrum associated with this tumor, we describe a normotensive patient in whom fever of unknown origin, anemia, thrombocytosis, abnormalities of hepatic function and pronounced elevation of the erythrocyte sedimentation rate were the presenting features of a norepinephrine- and dopamine-secreting pheochromocytoma. Complete resolution of the fever and of the hematologic and biochemical abnormalities followed removal of this benign neoplasm.
