A recently published study of the management of low-grade cytologic smears compared immediate colposcopy to human papillomavirus (HPV) triage and entry cytology smears (conservative management) as three triage techniques for managing atypical squamous cells of undetermined significance (ASCUS) smears (Atypical Squamous Cells of Undetermined Significance/Low-grade Squamous Intraepithelial Lesion...

BACKGROUND Anal cancer, one of human papillomavirus (HPV) related malignancies, has increased in recent decades, particularly among men who have sex with men (MSM) and HIV-infected (HIV+) persons. We aimed to explore the prevalence of anal squamous intraepithelial lesions (ASIL) using Papanicolau (Pap) screening among MSM in northern Thailand and its associated factors. METHODS Two hundreds M...

We report the prevalence of human papillomavirus type 16 (HPV-16) variants in women with cervical lesions from the Federal District, Central Brazil. We analyzed 34 HPV-16 samples, identifying the sequence variations of E6 and L1 genes and correlating variant frequency with disease status. The most prevalent HPV-16 variant was the European (50%), followed by Asian-American (41.2%), African-1 (5....

PURPOSE GRIM-19 has been shown to be down-regulated in cervical cancers. This study investigated the expression of GRIM-19 in cervical intra-epithelial neoplasias and its association with high-risk human papillomavirus (HR-HPV) infection. METHODS The expression of GRIM-19 was assessed in cervical exfoliated cells and cervical intra-epithelial neoplasia tissues by immunohistochemistry, and the...

The primary squamous cell carcinoma of prostate is a rare tumor that its histogenesis has not been clearly identified. This tumor comprises 0.5 to 1 % of malignant tumors of prostate. In most cases, there exists a severe and atypical metaplasia. The case was a 66 years man that admitted for increased frequency of urination and a burning sensation. In initial examinations, because of the existe...

abstract-cervicovaginal cytology is still a widely used cancer screening method that is well established in most countries. the present study aims at detecting and classifying squamous intraepithelial abnormalities and effects of certain infectious agents, particularly the cytopathic effects of human papillomavirus (hpv) in a series of cervicovaginal smears, according to the bethesda system (tb...

A new tumor-associated antigen, MN, has been shown to be expressed in virtually all cervical carcinomas and the majority of cervical intraepithelial neoplasia, but not in normal cervices (S. Y. Liao et al., Am. J. Pathol., 145: 598-609, 1994). Therefore, we postulated that the exfoliative cells in cervical Papanicolaou (Pap) smears would reflect the MN immunoreactivity seen in the tissue sectio...

BACKGROUND HIV-positive women have a high prevalence of human papillomavirus (HPV) infection and are infected with a broader range of HPV types than HIV-negative women. It is not known to what extent these different types are associated with high-grade squamous intraepithelial lesions (HSIL) and cancer. METHODS Meta-analysis of HPV type-specific prevalence among HIV-positive women, stratified...
