Abstract
A 14 year old boy had suffered from gross intermittent painless hematuria since 4 month
before admission. The plain abdominal film showed calcification in bladder area. The
sonographic examination showed mass in antero-superior urinary bladder wall. A
cystoscopic examination revealed an exophytic mass in the anterior urinary bladder wall
with the biopsy result is urothelial papilloma. A transcutaneus resection was performed and
then was converted to a partial cystectomy because the mass was solid and not mucosal.
The specimen measures about 5,5 x 3,5 x 2 cm with pathologic result is cavernous
hemangioma. The patient recovered with no complications encountered.
