Correlation between koilocytes and human papillomavirus detection by PCR in oral and oropharynx squamous cell carcinoma biopsies
(Instituto Oswaldo Cruz, Ministério da Saúde, 2011-03-01)
The purpose of this study was to compare the histopathological analysis with polymerase chain reaction (PCR) methods to predict the presence of human papillomavirus (HPV) infection in oral squamous cell carcinoma biopsies. ...
Detection of HPV in mouth floor squamous cell carcinoma and its correlation with clinicopathologic variables, risk factors and survival
(Wiley-Blackwell, 2008-11-01)
The human papillomavirus (HPV) has been historically associated with head and neck cancers, although its role in oral carcinogenesis remains poorly defined. The purpose of this study was to investigate the prevalence of ...

Comparative analysis of cell proliferation ratio in oral lichen planus, epithelial dysplasia and oral squamous cell carcinoma
(Medicina Oral S L, 2009-11-01)
Background: Although oral lichen planus has been classified by the World Health Organization (WHO) as a potentially malignant disorder, such classification is still the target of much controversy. Aim: To evaluate the cell ...

Mesh cancer: long-term mesh infection leading to squamous-cell carcinoma of the abdominal wall
(2013-04-22)
Purpose: It is recognized that chronic inflammation can cause cancer. Even though most of the available synthetic meshes are considered non-carcinogenic, the inflammatory response to an infected mesh plays a constant ...
Squamous cell carcinoma arising in a multiple verrucous epidermal nevus
(Soc Brasileira Dermatologia, 2016)
Verrucous epidermal nevi are hamartomatous lesions of the epidermis that, unlike other epidermal nevi (such as sebaceous nevus or nevus comedonicus), are rarely associated with malignant neoplasms. The majority of squamous ...
Angiogenesis and skin carcinomas with skull base invasion: A case-control study
(Wiley-Blackwell, 2004-05-01)
Background. Some skin carcinomas may be very aggressive. Intensity of angiogenesis, measured by intratumoral vessel density using expression of CD34, has been associated with tumor aggressiveness. In this study, the ...
Expression of annexin A1 mRNA in peripheral blood from oral squamous cell carcinoma patients
(Elsevier B.V., 2010-01-01)
Several studies have been suggesting annexin A1 protein as an active player in tumorigenesis of many organs. Nevertheless, its tumor biomarker role has been mainly studied in tissues by immunohistochemistry or cell culture. ...
