Transitional cell carcinoma in distal urethra after previous excision of HPV related condyloma: Is there a link between human papilloma virus (HPV) and transitional cell carcinoma (TCC)?

This article focuses on a clinical case involving a 56-year-old man who initially underwent surgical excision of HPV-related condyloma acuminatum lesions at the distal urethra, followed by a recurrence diagnosed as low-grade noninvasive papillary urothelial carcinoma (TCC) at the same site. The case highlights the unusual occurrence of urothelial carcinoma in the distal urethra, an area typically lacking urothelium, and the presence of p16 immunohistochemical positivity, a marker associated with HPV-related oncogenic activity. While existing literature suggests a potential association between human papillomavirus (HPV) infection and transitional cell carcinoma, particularly in the bladder, definitive evidence remains inconclusive due to methodological variability. The report underscores the importance of heightened awareness for HPV infection prevention and TCC screening in patients with HPV-related lesions to improve early diagnosis and management.
