A 24-year-old male presented with following lesion on his genitalia, following intercourse with multiple sexual partners, and multiple times. Which human papilloma virus is the causative agent?
## **Core Concept**
The question revolves around the identification of a specific type of human papillomavirus (HPV) that causes genital lesions, particularly in the context of a patient with a history of multiple sexual partners. HPV is a significant cause of sexually transmitted infections (STIs) and is associated with various clinical manifestations, ranging from benign lesions to malignant transformations.
## **Why the Correct Answer is Right**
The correct answer, **HPV-6 and HPV-11**, are known to cause **genital warts** (condylomata acuminata), which are benign lesions that appear on the genitalia. These types of HPV are considered low-risk for causing cancer but are responsible for the majority of cases of genital warts. The patient's presentation with genital lesions and a history of multiple sexual partners increases the likelihood of acquiring HPV.
## **Why Each Wrong Option is Incorrect**
- **Option A:** HPV-16 and HPV-18 are considered high-risk HPV types, primarily associated with **cervical cancer** and other anogenital cancers, rather than benign genital warts.
- **Option B:** HPV-31 and HPV-33 are also classified as high-risk HPV types, similar to HPV-16 and HPV-18, and are not the primary cause of genital warts.
- **Option D:** HPV-2 and HPV-4 are more commonly associated with **common warts** (verruca vulgaris) rather than genital warts.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that while **HPV-6 and HPV-11** cause genital warts, **HPV-16 and HPV-18** are responsible for the majority of cervical cancer cases. The vaccine against HPV can protect against some of these types, emphasizing the importance of vaccination in preventing HPV-related diseases.
## **Correct Answer:** . **HPV-6 and HPV-11**
