Pseudoepitheliomatous Hyperplasia of the Larynx Requiring Total Laryngectomy.

BACKGROUND Pseudoepitheliomatous hyperplasia (PEH) is a reactive epithelial proliferation occurring secondary to infection, neoplasm, injury, and inflammation. The histopathological characteristics of PEH may lead to it being confused with well-differentiated squamous cell carcinoma (SCC). CASE REPORT We present here the case of a 57-year-old male patient, who was diabetic and a smoker, who presented with dysphonia.

BARHL1 Is Downregulated in Alzheimer's Disease and May Regulate Cognitive Functions through ESR1 and Multiple Pathways.

The Transcription factor BarH like homeobox 1 (BARHL1) is overexpressed in medulloblastoma and plays a role in neurogenesis. However, much about the BARHL1 regulatory networks and their functions in neurodegenerative and neoplastic disorders is not yet known. In this study, using a tissue microarray (TMA), we report for the first time that BARHL1 is downregulated in hormone-negative breast cancers and Alzheimer's disease (AD).

Biomarkers for the identification of precursor polyps of colorectal serrated adenocarcinomas.

Background: In contrast to conventional colorectal carcinomas (CCs), which develop through a so-called chromosome instability or suppressor phenotype pathway, the sequence of events leading from precursor polyps/adenomas to serrated adenocarcinomas (SACs), which are more aggressive and exhibit a poorer survival than CCs, is as yet not clearly defined. Here, we aimed at detecting protein and DNA biomarkers for SAC in a series of primary colorectal polyps.

Methods: In total 303 colorectal polyps were included: 121 serrated polyps (33 hyperplastic polyps, 37 sessile serrated adenomas (SSA), 51 traditional serrated adenomas (TSA)), 143 conventional polyps (72 tubular polyps, 34 tubulovillous polyps, 37 villious adenomas), and 39 bi-phenotypic serrated-conventional polyps.
