Objective:
To report on a case of hemangiopericytoma of the urinary bladder mimicking a urothelial tumor.
Methods:
A case of hemangiopericytoma arising from the urinary bladder in a 78-year-old man is described. The initial symptoms included gross hematuria, and it was confused with a urothelial tumor. The difficulty in making the diagnosis in regard to the site of origin and histological findings are discussed. The literature is briefly reviewed.
Results/Conclusions:
Ultrasound and urographic evaluation showed an intravesical mass which was suspected to be a urothelial tumor. The patient was submitted to transurethral surgery. Histological analysis and immunohistochemical techniques demonstrated a hemangiopericytoma.
