title: [A case of pelvic aggressive angiomyxoma involving urinary bladder].
abstract: A 23-year-old man visited hospital with the complaints of hematuria and miction pain. Computed tomography and magnetic resonance imaging of the pelvis showed a large pelvic tumor contiguous to the urinary bladder. Resection of the tumor with partial cystectomy was performed on February, 1998. Histopathological examination showed that the tumor composed of angiomyxoma infiltrating into the urinary bladder. The patient is alive without recurrence of aggressive angiomyxoma 12 months after surgery. To our knowledge, this is the first report in the Japanese literature of aggressive angiomyxoma involving the urinary bladder. Awareness of this uncommon neoplasma is important in the diagnosis of pelvic tumor to prevent an extensive surgery.
