Bladder leiomyoma, a rare benign tumor, is effectively treated with laparoscopic partial cystectomy. This minimally invasive approach offers good outcomes for patients with this smooth muscle tumor.

Area of Science:

  • Urology
  • Surgical Oncology
  • Pathology

Background:

  • Leiomyoma is the most common benign non-epithelial bladder tumor, originating from smooth muscle bundles.
  • While more common in females, it can occur in males, presenting with symptoms like chronic pelvic pain.

Observation:

  • A 38-year-old male presented with chronic pelvic pain, diagnosed via CT scan with a 2 cm exophytic bladder lesion.
  • The lesion protruded into the perivesical fat, necessitating surgical intervention.

Findings:

  • A laparoscopic partial cystectomy was successfully performed with simultaneous cystoscopic control, achieving negative margins.
  • Pathology confirmed a bladder leiomyoma, negative for mitosis/atypia, with immunohistochemistry positive for Actine and Vimentine, ruling out GIST.

Implications:

  • Laparoscopic partial cystectomy is an effective minimally invasive treatment for bladder leiomyoma.
  • This approach offers a good prognosis with a low risk of recurrence for bladder leiomyoma.
