Clear cell carcinoma of female urethral diverticulum--a case report

Abstract

Primary malignancies of female urethral diverticulum are rare. A well-documented female patient with primary clear cell carcinoma of the urethral diverticulum is presented here. A 65-year-old woman presented with frequency and voiding difficulty for 2 months. Physical examination showed a 4-cm mass protruding from anterior vaginal wall. Intravenous urography, magnetic resonance imaging, and cystoscopy showed a polypoid mass in urethral diverticulum. She then underwent anterior exenteration with ileal conduit diversion and urethrectomy. Pathology confirmed the diagnosis of clear cell adenocarcinoma with bladder neck invasion. She had no disease recurrence at 2-year follow-up. Careful clinical examination and image studies are helpful in making the preoperative diagnosis for the rare disease. Early radical surgery can achieve better survival.
