[Cavernous hemangioma of the bladder].

Objective: Certain pathologic entities should be ruled out in the diagnostic work up of hematuria, because they are so rare that if they would not share diagnostic tests with more frequent urological diseases they could be missed. The cavernous haemangioma of the bladder is one of them.

Methods: We report the case of a male patient presenting with rectal bleeding and hematuria with the diagnosis of rectal-vesical cavernous haemangioma.

Results: After 8 years of follow-up he did not need surgical treatment, only blood transfusions at the time of diagnosis. He has self limited episodes of hematuria not requiring aggressive therapy.

Conclusions: The cavernous haemangioma of the bladder is a rare disease presenting as bleeding bladder excrecent lesions that do not require surgery as first treatment option if the bleeding is not life-threatening.
