Haemangioma of the urinary bladder: a rare case report

Haemangioma of the urinary bladder is a rare vascular tukmor with a benign nature and a very wide age range. It accounts only 0.6% of bladder neoplasms and is therefore quite infrequently discussed in literature. It is also seen more often among men than among women. Histologically classified as cavernous, capillary or arteriovenous, this lesion resembles haemangiomas at any other site of the human body. Clinically manifested with painless haematuria haemangioma of the urinary bladder is undoubtedly of a huge clinical importance as one of the benign causes of bleeding in the urinary tract. We report a case of bladder haemangioma in a 64-year-old man presented to the hospital with dysuria. Pathologic examination of the bladder biopsy revealed typical histological features of haemangioma. In particular, lined by endothelial tumor cells cavernous spaces filled with blood and surrounded by fibrous tissue. After the histological examination of the taken biopsy, the patient was diagnosed with haemangioma of the urinary bladder, cavernous type.
