Cellular Classification of Penile Cancer

    Virtually all penile carcinomas are of squamous cell origin and include the following subtypes:

    • Verrucous carcinoma.[1]
    • Warty carcinoma (verruciform).[2]
    • Basaloid carcinoma.[3]

    Although they are less common subtypes, warty carcinoma and basaloid carcinoma appear to be more highly associated with human papillomaviruses (HPV), particularly HPV 16, than typical squamous cell carcinoma or verrucous carcinoma of the penis.[3,4,5]
