Patients with a pheochromocytoma usually present with intractable hypertension, postural hypotension, headaches, and palpitations, with intractable hypertension being the predominant symptom. When the tumor is located in the urinary bladder, symptoms may be induced by micturition. Herein, we report a patient with systemic lupus erythematosus and a bladder pheochromocytoma without hypertension or symptoms induced by micturition. Instead, he presented with postural hypotension and palpitations.
