Condyloma accuminatum caused most commonly by human papilloma virus (HPV) types of
**Core Concept**
Condyloma acuminatum, also known as genital warts, is a sexually transmitted infection caused by human papillomavirus (HPV). HPV is a DNA virus that infects epithelial cells and leads to abnormal cell growth, resulting in wart-like lesions. The virus has over 100 types, but certain types are more commonly associated with condyloma acuminatum.
**Why the Correct Answer is Right**
The most common types of HPV responsible for condyloma acuminatum are HPV-6 and HPV-11. These low-risk HPV types primarily infect the epithelial cells of the skin and mucous membranes, leading to the development of genital warts. The exact mechanism of how HPV causes condyloma acuminatum involves the integration of the viral genome into the host cell, which disrupts normal cellular function and leads to uncontrolled cell growth. The resulting lesions are typically painless and can appear on the genitals, anus, or perineum.
**Why Each Wrong Option is Incorrect**
**Option A:** HPV-16 and HPV-18 are high-risk HPV types commonly associated with cervical cancer, not condyloma acuminatum.
**Option B:** HPV-2 is another low-risk type, but it's less commonly associated with condyloma acuminatum compared to HPV-6 and HPV-11.
**Option C:** HPV-5 is a rare type that's more commonly associated with skin lesions in patients with epidermodysplasia verruciformis, a rare genetic disorder.
**Clinical Pearl / High-Yield Fact**
HPV-6 and HPV-11 are the most common types of HPV associated with condyloma acuminatum, and they can be detected using PCR (polymerase chain reaction) or HPV DNA testing. It's essential to diagnose and treat condyloma acuminatum promptly to prevent the spread of the infection and potential complications.
