Cell cycle control and its modulation in HPV infected cells

, 2010
A key effect of human papillomavirus (HPV) infection is to disrupt the normal cell cycle in order to subvert the cellular DNA replication machinery. Morphologically, condylomata induced by high and low risk HPV types cannot be distinguished and many ...

Squamous cell carcinoma of the lungs arising in recurrent respiratory papillomatosis

, 2010
Squamous papillomas of the lung are an uncommon feature of recurrent respiratory papillomatosis (RRP), occurring in fewer than 1% of cases. We describe an 18-year-old male patient with pulmonary papilloma who developed a fatal squamous cell carcinoma of ...

Diagnostic Accuracy of Entropy Based Image Analysis of Cervical Precancerous Cells

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
This work studies the correlation between the Bragg‐Williams order parameter (S2), as measured from a digital slide image, and the cytopathologic diagnoses of squamous cervical cytology and demonstrates the diagnostic accuracy of the S2 classification model. This image is an example of this approach for a “carcinoma in situ” cell image and demonstrates

Sublineage‐Specific A45S Polymorphism Alters the Biological Function of the Human Papillomavirus 11 E7 Protein

Journal of Medical Virology, Volume 98, Issue 6, June 2026.
ABSTRACT The E7 oncoprotein of human papillomavirus (HPV) plays a crucial role in viral pathogenesis and replication. Although it is generally highly conserved across HPV genotypes, naturally occurring E7 variants can display functional differences that may affect viral persistence, oncogenic potential, and host cellular responses.

High‐Risk Human Papillomavirus Types and Squamous Cell Carcinoma in Patients with Respiratory Papillomas

, 1999
Respiratory papillomas (RPs) are benign, virally induced tumors of the larynx and respiratory epithelium that may obstruct the airway and tend to recur frequently. RPs are thought to be the result of infection with the human papillomaviruses (HPVs) types

Squamous cell papilloma of esophagus.

Canadian journal of surgery. Journal canadien de chirurgie, 1979
Squamous cell papilloma of the esophagus is rare. Seven well-documented cases have been reported in the English literature. Three further cases are presented, in one of which symptoms were related to the tumour. Although there is no proof that this lesion is premalignant, coincident cancer must be excluded.
