Condyloma acuminatum, intraepithelial neoplasia, and squamous cell carcinoma are three relatively frequent vulvar lesions. Condyloma acuminatum is induced by low risk genotypes of human papillomavirus (HPV). Vulvar intraepithelial neoplasia (VIN) and squamous cell carcinoma have different etiopathogenic pathways and are related or not with high risk HPV types. The goal of this paper is to revie...

Materials and methods: A total of 3488 women who were undergoing routine cervical screening (1308 CC and 2180 LBC) were included in the initial screening. The results were assessed as either satisfactory or unsatisfactory. Satisfactory results were subdivided as negative, atypical squamous cells of undetermined significance (ASCUS), atypical squamous cells for which high-grade lesions could not...

To understand the potential role in cervical cancer development of the three most common high-risk human papillomavirus (HR-HPVs) in Thai women, HPV genotypes and viral genome statuses in different cervical lesions were investigated. Cervical tissues consisting of no cervical intraepithelial neoplasia (84 cases), grade I cervical intraepithelial neoplasia (176 cases), grade II-III cervical intr...

BACKGROUND The Cervical Cancer Database of the Brazilian National Health Service (SISCOLO) contains information regarding all cervical cytological tests and, if properly explored, can be used as a tool for monitoring and managing the cervical cancer screening program. The aim of this study was to perform a historical analysis of the cervical cancer screening program in Brazil from 2006 to 2013....

OBJECTIVE The objective of this study was to assess the potential of 3 spectroscopic techniques (intrinsic fluorescence, diffuse reflectance, and light scattering) individually and in combination (trimodal spectroscopy) for the detection of cervical squamous intraepithelial lesions. STUDY DESIGN The study was conducted with 44 patients who underwent colposcopy for the evaluation of an abnorma...

Squamous cell carcinoma of the vulva occurs predominantly in the older age group. Although the incidence rate of vulvar intraepithelial neoplasia is increasing, that of squamous cell carcinoma of the vulva is declining, reflecting earlier detection and more successful treatment. In addition to human papillomavirus infection, cigarette smoking is a putative risk factor for vulvar squamous cell c...

85 Abstract Objective: We intended to study the cellular proliferation by means of Ki-67 labeling index and the protein product overexpression of p53 in a series of oral intraepithelial lesions and squamous cell carcinoma, to evaluate the potential association between their histologic grades and the expression of the two markers. The expression of these markers on sections taken from hyperplast...

It has long been speculated that underlying variations in tissue anatomy affect in vivo spectroscopic measurements. We investigate the effects of cervical anatomy on reflectance and fluorescence spectroscopy to guide the development of a diagnostic algorithm for identifying high-grade squamous intraepithelial lesions (HSILs) free of the confounding effects of anatomy. We use spectroscopy in bot...

although the diagnostic category of atypical squamous cells of undetermined significance (ascus) has been known since 1988, its use and appropriate clinical follow up and management still remains controversial. this study was carried out to evaluate the diagnostic value of ascus, using cytohistologic correlation. a retrospective review of archival materials in our cytology laboratory files was ...
