Summary
Urinary bladder hemangiomas are rare tumors. This study found that small bladder hemangiomas treated with biopsy and fulguration have a favorable long-term outcome with no recurrences observed.
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Urinary bladder hemangiomas are uncommon neoplasms.
- Long-term outcomes for patients with bladder hemangiomas are not well-established.
Purpose of the Study:
- To evaluate the clinical and pathological findings of bladder hemangiomas.
- To determine the long-term outcomes of patients diagnosed with vesical hemangioma.
Main Methods:
- Retrospective chart review of 19 patients with histologically confirmed bladder hemangioma treated at Mayo Clinic (1932-1998).
- Classification of hemangioma types (cavernous, capillary, arteriovenous).
- Mean follow-up duration of 6.9 years.
Main Results:
- The average age at diagnosis was 58 years, with a male predominance (3.7:1).
- Macroscopic hematuria was the common presentation; endoscopic findings were often nonspecific.
- Most tumors were small (median 0.7 cm), solitary, and located on posterior/lateral walls. Cavernous type was most frequent (15/19 cases).
Conclusions:
- Bladder hemangiomas demonstrate a favorable prognosis.
- Biopsy and fulguration are effective treatments for small bladder hemangiomas, with no observed recurrences in this cohort.
