**Core Concept**
Verrucous carcinoma of the penis is a rare, low-grade variant of penile squamous cell carcinoma. It typically presents as a well-demarcated, verrucous lesion on the glans or prepuce. The etiology of verrucous carcinoma is often linked to human papillomavirus (HPV) infection, particularly types 6 and 11.

**Why the Correct Answer is Right**
Verrucous carcinoma is characterized by its slow growth and local invasiveness, often causing significant destruction of penile tissue. The lesion typically exhibits a characteristic "pushing" border and minimal cytological atypia. The role of HPV in the development of verrucous carcinoma is supported by the presence of HPV DNA in tumor cells and the association with other HPV-related lesions.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect, as verrucous carcinoma is not primarily associated with human immunodeficiency virus (HIV) infection.
**Option B:** Incorrect, as syphilis is a different sexually transmitted infection that can cause penile lesions, but it is not the primary cause of verrucous carcinoma.
**Option C:** Incorrect, as squamous cell carcinoma, while a type of penile cancer, is a more aggressive and high-grade variant than verrucous carcinoma.

**Clinical Pearl / High-Yield Fact**
HPV-related penile lesions, including verrucous carcinoma, are often associated with a history of genital warts or other HPV-related lesions. A thorough sexual history and physical examination are essential in diagnosing and managing penile cancer.

**Correct Answer: D. Human Papillomavirus (HPV)**
