Bradley B Bryan, Stuart J Schnitt and Laura C Collins. Department of Pathology, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, MA, USA. Abstract: Basal-like carcinomas have recently been identified in gene expression profiling studies as a subtype of invasive breast cancer. These lesions are estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and HER2-negative (triple negative), andSigueSigue leyendo «Ductal carcinoma in situ with basal-like phenotype: a possible precursor to invasive basal-like breast cancer.»

Cervical cancer prevention and screening: the role of human papillomavirus testing. Review.
Abstract Key content An organised screening programme has reduced the incidence of cervical cancer in the UK. Cervical screening aims to detect and treat premalignant, low- or high-grade disease. Oncogenic or high-risk human papillomaviruses (HR-HPV) account for over 99.7% of cervical cancer cases; the most common subtypes are HPV-16, 18, 31, 33 and 45.SigueSigue leyendo «Cervical cancer prevention and screening: the role of human papillomavirus testing.

Non-cervical human papillomavirus-related disease. Review.
Abstract. Key content. Human papillomavirus (HPV) is associated with neoplastic disease at sites other than the cervix. Cancer caused by HPV may behave differently to other cancers at the same site. The presence of HPV alone is not sufficient to demonstrate a causal association. HPV vaccination has the potential to impact on disease burden beyondSigueSigue leyendo «Non-cervical human papillomavirus-related disease. Review.»
The Natural History of Vulvar Intraepithelial Neoplasia, Differentiated Type: Evidence for Progression and Diagnostic Challenges.
Middlemore Hospital (S.M.B.), Auckland, New Zealand; Department of Gynecological Oncology (L.J.E., K.L.F., R.W.J.), Auckland City Hospital, Auckland, New Zealand. The authors declare no conflict of interest. Abstract. Squamous cell carcinoma of the vulva (SCCV) develops through either human papillomavirus (HPV)-dependent or HPV-independent pathways. Approximately 60% of SCCV arise independently of HPV, commonly in a backgroundSigueSigue leyendo «The Natural History of Vulvar Intraepithelial Neoplasia, Differentiated Type: Evidence for Progression and Diagnostic Challenges.»

Molecular Pathways in Gliomagenesis and Their Relevance to Neuropathologic Diagnosis.
Abstract. Gliomas are a large and diverse group of primary brain tumors that include those that are diffusely infiltrative and others that are well-circumscribed and low grade. Diffuse gliomas are currently classified by the World Health Organization as astrocytomas, oligodendrogliomas, or oligoastrocytomas and range in grade from II to IV. Glioblastoma (GBM), World Health OrganizationSigueSigue leyendo «Molecular Pathways in Gliomagenesis and Their Relevance to Neuropathologic Diagnosis.»
Melanocytic Nevi of Special Sites.
Melanocytic Nevi of Special Sites. Ahn, Christine S. MD; Guerra, Analia MD; Sangüeza, Omar P. MD. Abstract: Melanocytic nevi located on specific regions of the body can demonstrate unusual histopathological features such as asymmetry, irregular nesting patterns, pagetoid spread, cytologic atypia, and rarely, mitotic activity. However, despite these features that may raise concern forSigueSigue leyendo «Melanocytic Nevi of Special Sites.»
