[A case of vaginal implantation of transitional cell carcinoma of the bladder]

Bladder and vaginal transitional cell carcinoma: A case report

The involvement of the female genital tract in transitional cell carcinoma (TCC) has not been fully elucidated in women, although involvement is usually associated with a poor prognosis. The vagina, in particular, is considered to be the most commonly affected gynecological organ, with an incidence of 4% of total TCC cases. The pathogenesis of vaginal TCC is challenging to determine, although it is essential for the adequate management of the tumor and to determine the appropriate treatment. The present study reports a case of bladder TCC and metachronous vaginal TCC. The patient had a history of high risk non muscle invasive bladder cancer treated by BCG and presented with a recurrent carcinoma in situ. A novel cycle of BCG was initiated but the patient had a persistent disease and a palpable mass on bimanual examination. Radical anterior pelvectomy and bilateral pelvic and inguinal lymph node dissection was performed revealing the presence of TCC of the bladder neck and the invasion into the anterior vaginal wall. The differences between local vaginal invasion and the metastatic spread from a primary bladder TCC, the occurrence of a second primary vaginal tumor and the direct implantation of TCC via urine that contains transitional cancer cells were reviewed and analyzed. Finally, a management plan was determined.

Non-muscle invasive bladder cancer with concomitant vaginal urothelial carcinoma: a case report and review of the literature

A 74-year-old female was referred to our hospital for non-muscle invasive bladder tumors initially treated at another hospital. Preoperatively, computed tomography and magnetic resonance imaging demonstrated non-muscle invasive bladder tumors and a vaginal tumor. A second transurethral resection of the bladder tumors, transvaginal tumor resection, and systemic chemotherapy were performed. The histopathological appearances of both tumors were very similar and the diagnoses were urothelial carcinoma (UC). The pathogenesis of the vaginal UC was considered to be the primary UC or metastasis from the bladder UC. Vaginal UC is extremely rare and this is only the 15th report in the literature.
