A 49-year-old man was hospitalized with the chief complaint of coagulation in urine. The patient was not hypertensive.

Transurethral resection of the tumor in the urinary bladder was performed. The histopathological diagnosis indicated pheochromocytoma. Blood pressure was stable. After operation, the patient's course was uneventful, and there has been no recurrence for one year after surgery. This patient is the 52nd patient with pheochromocytoma of the urinary bladder reported in the Japanese literature.
