Female Prostate? - Clear Cell Adenocarcinoma of Female Urethra

ABSTRACT

Clear cell adenocarcinoma of the female urethra is extremely rare. Because the primary urethral carcinomas are rare, standard diagnostic algorism and management has not been established yet. We report a case of clear cell adenocarcinoma of the proximal urethra in a 76-year-old female. She was presented with voiding difficulty for several years after pubovaginal sling operation due to stress urinary incontinence twelve years ago. Before this period, she had managed with medication for detrusor hypocontractility. Recently she complained bloody vaginal discharge, and her vaginal examination revealed palpable mass on the anterior vaginal wall. Pelvic MRI showed a 5×4.5cm sized tumor surrounding the proximal urethra which was mimicking prostate with no lymphadenopathy. Biopsy of the mass confirmed it to be clear cell adenocarcinoma. She underwent anterior pelvic exenteration and ileal conduit with bilateral pelvic lymph node dissection. The patient received adjuvant radiotherapy and chemotherapy as treatment. We should carefully evaluate patients with voiding symptom after anti-incontinence surgery and multimodal treatment should be applied for locally advanced urethral carcinoma.
