ABSTRACT Vulvar cancer, a rare gynecological malignancy, accounts for 3-5% of cases and is most commonly squamous cell carcinoma. Prognosis is poorer in cancers unrelated to human papillomavirus (HPV), often associated with chronic inflammation. We report the case of a 42-year-old woman from São Paulo, Brazil, who presented with a vulvar lesion initially misdiagnosed as an ingrown hair. Despite treatment, the lesion progressed, and subsequent evaluation revealed invasive squamous cell carcinoma. Biopsy confirmed HPV-independent disease, with immunohistochemistry demonstrating aberrant p53 […]

Highlights Twenty-eight cases of bladder squamous cell carcinoma cases were evaluated for p16, p53, p63 immunohistochemistry, and HPV PCR. Neither direct HPV detection nor its indirect marker (p16) was identified in most cases. Decision trees constructed described the relationships of a variety of clinicopathological features with high classification accuracy.   ABSTRACT Objective To investigate the expression of human papillomavirus (HPV), p16, p53, and p63 in non-schistosomiasis-related squamous cell carcinoma of the bladder and to develop an accurate and automated tool […]

Objetivo : Determinar a prevalência de doenças sexualmente transmissíveis em mulheres atletas. Métodos : Estudo observacional, de corte transversal, que incluiu 50 mulheres atletas com idade média de 20±3 anos. Realizaram-se colposcopia, coleta de colpocitologia oncótica cérvico-vaginal e pesquisa para Chlamydia trachomatis, papilomavírus humano e Neisseria gonorrhoeae, pelo método do reação de cadeia de polimerase. Amostras de sangue foram obtidas para pesquisa de vírus da imunodeficiência humana, sífilis, hepatite B e C. As atletas que apresentaram doenças clínicas ou laboratorialmente […]
