Intravesical human papillomavirus (IHPV) infection–endoscopic resection

INTRODUCTION

Although HPV infections are common, intravesical HPV is a rare condition, with only 20 reported cases (11. Massé S, Tosi-Kruse A, Carmel M, Elhilali M. Condyloma acuminatum of bladder. Urology. 1981;17:381-2.).

Objectives: The aim of this video is to present a case treated with transurethral resection (TR).

RESULTS

A 38-year-old woman, with a history of urinary tract infections. She denied other diseases and complained of painful urination. The genital examination, cervical cytology and colposcopy were normal. Urinalysis showed leukocytosis, but a negative culture. The ultrasound was normal. A cystoscopy was performed, showing polypoid growth on the bladder mucosa followed of the TR. Histopathologic analysis (HA) confirmed IHPV (in situ hybridization positive for 6, 18, 31 subtypes), associated a Bladder Squamous Metaplasia (BSM). The patient recurrence-free was for 5 years when a cystoscopy demonstrated BSM, which was resected. The patient had not any other sites (urethral, genital or anal) of recurrence during the period of follow-up.

DISCUSSION

The condyloma, caused by types 6 and 11, is more frequent in the genital mucosa and anal area (11. Massé S, Tosi-Kruse A, Carmel M, Elhilali M. Condyloma acuminatum of bladder. Urology. 1981;17:381-2., 22. Barber NJ, Kane TP, Conroy B, Britton JP. Condyloma acuminatum-like lesion of the urinary bladder progressing to invasive spindle cell carcinoma. Scand J Urol Nephrol. 2003;37:512-4.). IHPV presents with a polypoid pattern, often related to warts in the urethra. The clinical presentation includes hematuria, dysuria, fever and pelvic pain (11. Massé S, Tosi-Kruse A, Carmel M, Elhilali M. Condyloma acuminatum of bladder. Urology. 1981;17:381-2., 22. Barber NJ, Kane TP, Conroy B, Britton JP. Condyloma acuminatum-like lesion of the urinary bladder progressing to invasive spindle cell carcinoma. Scand J Urol Nephrol. 2003;37:512-4.). HA evaluation shows hyperproliferation of metaplasic squamous cells, the transition to the normal epithelium is sudden, with no submucosal invasion. This pattern excludes squamous cell carcinoma (SCC). A standard treatment was not established. TR has also been successfully used (11. Massé S, Tosi-Kruse A, Carmel M, Elhilali M. Condyloma acuminatum of bladder. Urology. 1981;17:381-2.), and radical cystectomy was indicated when the lesion was associated with SCC (33. White R, Donnellan S, Leong T. Complete resolution of urinary bladder condyloma acuminatum following definitive chemoradiotherapy for anal cancer. BJU Int. 2011;108:38-41.). Since the cytotoxic immune responses against malignant and virally transformed cells appear to be similar, local application of BCG might also be effective in the adjuvant treatment of recurrent condylomata (44. Böhle A, Doehn C, Kausch I, Jocham D. Treatment of recurrent penile condylomata acuminata with external application and intraurethral instillation of bacillus Calmette-Guerin. J Urol. 1998;160:394-6.).

CONCLUSIONS

TR may be a safe option for definitive IHPV treatment. However, the patients must be followed as in cases of the superficial carcinoma of transitional epithelium.

EDITORIAL COMMENT

Authorship SCIMAGO INSTITUTIONS RANKINGS

This interesting video by Almieda and colleagues highlights a rare occurrence of HPV infection within the bladder mucosa diagnosed after transurethral resection. It further characterizes the diffuse nature of HPV-associated manifestations, which can cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vuluvar, vaginal, and penile malignancies. In this particularly case, the patient remained recurrence-free for 5 years, which reinforces the heterogeneity of HPV-associated disease and its malignant potential based on the anatomic site of infection (11. Giuliano AR, Nyitray AG, Kreimer AR, Pierce Campbell CM, Goodman MT, Sudenga SL, et al.: EUROGIN 2014 roadmap: differences in human papillomavirus infection natural history, transmission and human papillomavirus-related cancer incidence by gender and anatomic site of infection. Int J Cancer. 2015;136:2752-60.). We applaud the authors for their novel work, which adds to the body of literature regarding potential sites of HPV-related disease and its differing natural history based on the site of infection.
