A 4-year-old child presents with hoarseness since 6 months of age. On laryngoscopy, there are bilateral wart-like lesions on the vocal folds. What is the most likely causative organism?
- A Human papillomavirus types 6 and 11 ✓
- B Candida albicans
- C Epstein-Barr virus
- D Respiratory syncytial virus
Correct answer: A. Human papillomavirus types 6 and 11
Explanation
Juvenile recurrent respiratory papillomatosis (RRP) is caused by human papillomavirus (HPV) types 6 and 11, acquired vertically during delivery through an infected birth canal. It presents with hoarseness and stridor due to wart-like lesions on the vocal folds, most commonly at the anterior commissure. The condition has a tendency to recur and may require repeated surgical debridement. HPV vaccination may help prevent future cases.
