Tongue Squamous Cell Carcinoma and Oral Lichen Planus: A Rare Case Report of a Pregnant Woman.

Squamous cell carcinoma (SCC) of oral mucosa is increasingly affecting younger individuals, particularly in the tongue. SCC can develop from disorders like oral lichen planus (OLP). This case highlights the first known instance of OLP and SCC in a pregnant woman, suggesting hormonal changes and HPV as possible risk factors.

Activity of apremilast in a patient with severe pemphigus vulgaris: case report.

Introduction: Although the treatment for pemphigus vulgaris (PV) has been revolutionized by the use of rituximab combined with corticosteroids, new effective therapies with a better safety profile are needed.

Observation: A 67-year-old woman was diagnosed with severe mucosal PV, which was initially misdiagnosed as atypical Behçet's disease. Following an unsuccessful colchicine treatment, significant improvement was observed upon the introduction of apremilast: reduced pain, fewer lesions, and a stabilized weight.

: a confirmed predisposing gene for adenomatous polyposis.

Background: The gene is part of the DNA mismatch repair system, but has never been shown to be involved in Lynch syndrome. A first report of four patients from two families, bearing biallelic germline variants, with a phenotype of attenuated colorectal adenomatous polyposis raised the question of its involvement in hereditary cancer predisposition. The patients' tumours exhibited elevated microsatellite alterations at selected tetranucleotide repeats (EMAST), a hallmark of deficiency.

Time-Dependent Efficacy of Checkpoint Inhibitor Nivolumab: Results from a Pilot Study in Patients with Metastatic Non-Small-Cell Lung Cancer.

Hypothesis: Prior experimental and human studies have demonstrated the circadian organization of immune cells' proliferation, trafficking, and antigen recognition and destruction. Nivolumab targets T(CD8) cells, the functions, and trafficking of which are regulated by circadian clocks, hence suggesting possible daily changes in nivolumab's efficacy. Worse progression-free survival (PFS), and overall survival (OS) were reported for malignant melanoma patients receiving more than 20% of their immune checkpoint inhibitor infusions after 16:30 as compared to earlier in the day.

Over 90% of cases of Microscopic Colitis can be diagnosed by performing a short colonoscopy.

Aims: To determinate the topographical distribution of key diagnostic histological features of lymphocytic colitis (LC) and collagenous colitis (CC) and to establish what correlations may exist between the histological findings and the causes and severity of MC.

Patients And Methods: Patients with MC were included in a prospective multicentre French study from September 2010 to October 2012. MC was diagnosed by performing total colonoscopy with multiple biopsies of the rectum and colon collected in separate jars and analyzed separately for each site (descending and sigmoid colon, transverse colon, ascending colon).

High prevalence of deficient mismatch repair phenotype and the V600E BRAF mutation in elderly patients with colorectal cancer.

Aims: Colorectal cancer (CRC) occurs mostly in the elderly. However, the biology of CRC in elderly has been poorly studied. This study examined the prevalence of deficient mismatch repair phenotype (dMMR) and BRAF mutations according to age.

Deficient mismatch repair phenotype is a prognostic factor for colorectal cancer in elderly patients.

Objective: About 15% of colorectal adenocarcinomas have a deficient DNA mismatch repair phenotype. The frequency of deficient DNA mismatch repair tumours increases with age due to the hypermethylation of hMLH1 promoter. The study aimed to determine the prognostic value of deficient DNA mismatch repair phenotype in elderly patients.

Pleomorphic hyalinizing angiectatic tumor of soft parts: ultrastructural analysis of a case with original features.

Pleomorphic hyalinizing angiectatic tumor, a rare neoplasm of uncertain lineage resembling malignant fibrous histiocytoma and schwannoma, was first described in 1996 by M. E. F.

[Post-cholecystectomy amputation neuroma of the common bile duct with obstructive jaundice].

Amputation neuroma of the common bile duct after surgery is a rare and mostly asymptomatic lesion. A 60-year old patient presented with obstructive jaundice three months after a cholecystectomy for symptomatic gallstones. Imaging investigations showed common extrahepatic bile duct stenosis.

Implication of tumstatin in tumor progression of human bronchopulmonary carcinomas.

The NC1 domain of alpha3 chain of type IV collagen, namely tumstatin, has been shown to display specific anti-angiogenic properties by inhibiting endothelial cells' proliferation and inducing their apoptosis via an interaction with alphavbeta3 integrin. Until now, the tumstatin anti-angiogenic effect has only been shown by in vitro studies or mouse xenograft experiments. In the present study, we examined the expression of tumstatin in relationship with tumor vascularization in 34 bronchopulmonary human carcinomas.

Recurrent human papillomavirus infection detected with the hybrid capture II assay selects women with normal cervical smears at risk for developing high grade cervical lesions: a longitudinal study of 3,091 women.

To test the reliability of the Hybrid Capture II (HC-II) assay detecting 13 high-risk human papillomavirus (HR-HPV) types for the screening of cervical lesions, we monitored by cytology, HR-HPV testing, colposcopy and biopsy, 3,091 women with normal smears at the first entry. Our primary endpoint was clinical progression defined as the presence of a high-grade lesion (HGSIL) at the biopsy. In our population of 659 HR-HPV-infected women, 241 (36.

Usefulness of DNA ploidy measurement on liquid-based smears showing conflicting results between cytology and high-risk human papillomavirus typing.

To improve the positive predictive value (PPV) for high-risk human papillomavirus (HR-HPV) in primary screening, DNA ploidy was measured on the same liquid-based sample by image cytometry in 984 cases showing discrepancies between cytology and HR-HPV testing. Of the conflicting results, 14.5% corresponded to a cytologic lesion (from atypical squamous cells of undetermined significance to high-grade squamous intraepithelial lesion [HSIL]) without HPV detected, and 85.
