Abstract
Purpose

Laryngeal papillomatosis is the most common benign tumor of the larynx of children. It is characterized by the development of exophytic proliferative lesions in the mucosa of the airways. Human papillomavirus (HPV) has been recognized as a causal agent among which HPV types 6 and 11 are the most frequently implicated. This disease affects the vocal cords and other important functions of the child. The difficulty of treatment is related to the high recurrence of papilloma growth after surgical removal. The objective of this study was to describe the implication of HPV6 and HPV11 in cases of laryngeal papillomatosis histologically confirmed in Ouagadougou.

Materials and methods

This was a descriptive cross-sectional study based on histologically diagnosed archival tissue; obtained in the last ten years (2007 to 2017) in the anatomy and cyto-pathology laboratories in Burkina Faso. These fixed and paraffin-embedded tissues were deparaffinized with xylene before HPV DNA extraction; then HPV6 and HPV 11 were identified by real-time multiplex PCR.

Results

The prevalence of low-risk HPV infection (HPV-LR) was 54.84% in histologically confirmed laryngeal papillomatosis in Ouagadougou. Among the HPV-LR positive samples, HPV6 and HPV11 genotype prevalence's were respectively 41.17% and 35.3% while the HPV6 / HPV11 co-infection was 23.53%.

Conclusions

The results show the implication of HPV6 and HPV11 in laryngeal papillomatosis in Burkina Faso with a high prevalence.
