However, it seems that it did not work well during the process. In this report, multiple EP was first described as EPS. HPV is now considered to be closely related to EP and esophageal cancer and was suggested as one of the etiological factors [18, 19]. Squamous cell papilloma arising from skin consists of hyperplastic epithelium arranged in prominent folds with fibrovascular stroma. Because of the extending growth pattern, papillomas are uncountable. Fragments of benign endocervix and squamous epithelium with mucus and mild chronic cervicitis. We can speculate that to some extent, EPS can co-exist with the respiratory system papillomas when HPV positive. Inverted squamous cell papillomas with mild cytologic atypia may be indistinguishable from invasive squamous cell carcinoma. Uterine cervix Surface epithelium is not commonly proliferative.

Pap smear: Do I need one if I'm a virgin? Int J Pediatr Otorhinolaryngol. HPV can be grouped as high or low risk according to their contribution to malignant changes. WebStratified squamous epithelium: This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or Mucocutaneous papillomas are a common finding of the Goltz syndrome, and EPS is a rare manifestation (Table 2). Well-differentiated squamous cell carcinoma can be papillary and endobronchial but usually demonstrates malignant cytologic features in addition to irregular infiltrating nests of cells within desmoplastic stroma. https://doi.org/10.1186/s13023-023-02703-8, DOI: https://doi.org/10.1186/s13023-023-02703-8.

Am J Dis Child. Morris [33] proposed that when newborns passage through an HPV infected canal, the transmission may occur in the upper respiratory/digestive tracts by contamination.
