Laryngeal papillomas caused by which HPV?
## **Core Concept**
Laryngeal papillomas, also known as recurrent respiratory papillomatosis (RRP), are benign tumors caused by infection with certain types of the human papillomavirus (HPV). The condition often leads to voice changes and can cause significant distress due to its recurrent nature. HPV types 6 and 11 are most commonly associated with this condition.
## **Why the Correct Answer is Right**
The correct answer, **HPV 6 and 11**, is right because these two types of HPV are well-documented to cause recurrent respiratory papillomatosis (RRP) or laryngeal papillomas. These types of HPV are considered low-risk for causing malignant transformation but are significant for their ability to cause recurrent and sometimes severe respiratory and vocal cord lesions.
## **Why Each Wrong Option is Incorrect**
- **Option A:** HPV 16 and 18 are primarily known for their association with cervical cancer and other anogenital cancers. They are considered high-risk HPV types, not commonly linked to laryngeal papillomas.
- **Option B:** While there are numerous HPV types, types 16 and 31 are not specifically identified as common causes of laryngeal papillomas. HPV 31 is also considered a high-risk type, similar to HPV 16 and 18.
- **Option D:** HPV 33 and 45 are also high-risk types, primarily associated with cervical and other cancers, not typically with laryngeal papillomas.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **HPV 6 and 11** are the primary causes of recurrent respiratory papillomatosis (RRP), a condition that can lead to significant morbidity due to its recurrent nature and potential for airway obstruction. The management often involves surgical removal of the papillomas and, in some cases, adjuvant therapies to reduce recurrence.
## **Correct Answer:** . HPV 6 and 11
