chondroectodermal dysplasia (ellis-van creveld syndrome) is a rare autosomal recessive congenital abnormality. this syndrome is characterized by a spectrum of clinical findings, among which chondrodystrophy, polydactyly, ectodermal dysplasia, and congenital cardiac anomalies are the most common. it is imperative to not overlook the cardiac complications in patients with this syndrome during den...

hypohidrotic ectodermal dysplasia (hed) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. the phenotype of hed is associated with mutation in eda, edar, edaradd and nemo genes, all of them disruptingnf-κb signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. here w...

OBJECTIVE To describe an unusual variant of oral epithelial dysplasia and to provide an appraisal of its immunohistochemical profile. STUDY DESIGN An unusual form of epithelial dysplasia, which we have termed adenoid dysplasia, was evaluated for staining of cytokeratins AE1/AE3, vimentin, E-cadherin, and β-catenin. The immunohistochemical results were compared with those observed in moderate ...

Incidences and morphological features of thyroid proliferative lesions induced by carcinogens in Wistar Hannover GALAS rats (GALAS rats) showing normal growth with or without thyroid dysplasia were examined. All thyroid tissue samples were obtained from our recently conducted study using male GALAS rats treated with 5 carcinogens according to the medium-term multiorgan carcinogenicity bioassay ...

Serial sections of 812 rectal biopsy specimens from 356 Crohn's disease patients were analysed for mucosal epithelial dysplasia. Dysplasia was found in 18 patients (5%), with four showing dysplasia on repeat biopsy specimen. In these 22 biopsy specimens the dysplasia was mild in 13, moderate in nine, and severe in none. Subsequently, three patients (17%) developed neoplasms including carcinoma ...

In the Norwegian Cervical Cancer Screening Programme tests for detection of human papillomavirus (HPV) are used to triage women with minor cytological cervical lesions. The material in this study comprises samples from 1 798 women in the period 2006-08. The HPV test was performed according to the guidelines of the Norwegian Cancer Registry. The HPV mRNA test (PreTect HPV-Proofer) detects and ty...

Morphologic dysplasia remains the criterion standard of cancer risk in Barrett esophagus but poses many challenges including distinction from reactive inflammatory change. Gastric foveolar dysplasia, a newly described subtype comprising 15% to 20% of Barrett dysplasia, overlaps with reactive cardiac mucosa in gastroesophageal reflux disease (GERD). Despite the clinical importance of accurate di...

BACKGROUND Renal dysplasia is the most important cause of end-stage renal disease in children. The histopathological characteristic of dysplasia is primitive tubules with fibromuscular disorganization. Renal dysplasia often includes metaplastic cartilage. Metaplastic cartilage in renal dysplasia has been explained as occurring secondary to vesicoureteral reflux (VUR). Additionally, renal dyspla...

Activation of the angiogenic process occurs during tumorigenesis, as does disturbance of cell proliferation and apoptosis. Seeking a potential correlation, we investigated tumor cell apoptosis, proliferation, and angiogenesis in the adenoma-carcinoma sequence of colorectal carcinogenesis using an in situ apoptosis detection kit and MIB-1 and anti-CD34 antibodies in 27 adenomas with low dysplasi...
