Abstract

Introduction: Condyloma acuminatum usually occurs in the external genitalia and rarely in the bladder mucosa. Here, we report a case of condyloma acuminatum of the bladder that was detected concurrently with urothelial carcinoma.

Case presentation: A 42-year-old man was referred to our urology department with positive urine cytology for urothelial carcinoma. Cystoscopy revealed a broad-base nonpapillary bladder tumor. The patient underwent a transurethral resection of the bladder tumor. Pathological examination revealed urothelial carcinoma, high-grade pT1, and concurrent resection of condyloma acuminatum. DNA was extracted from the paraffin-embedded transurethral resection of the bladder tumor tissue specimens. HPV11 was detected in condylomas by PCR and in situ hybridization, whereas HPV was not detected in urothelial carcinomas.

Conclusion: We report a rare case of condyloma acuminatum of the bladder that was concurrently diagnosed with urothelial carcinoma from the same site.

Keywords: bladder; condyloma acuminatum; human papilloma virus; urothelial carcinoma.
