Among oral lesions, we encounter a series of malignant epithelial lesions that go through clinical and histopathologic processes in order to be diagnosed. Identifying these processes along with the etiology knowledge of these lesions is very important in prevention and early treatments. Dysplasia is the step preceding the formation of squamous cell carcinoma in lesions which have the potential ...

Epithelial inclusions were detected in myocardium of a 2-month-old male Holstein calf. Microscopically,nonpurulent myocarditis along with focal tubular and acinar structures covered with cuboidal epithelial cellswas seen in the myocardium. Most tubular and acinar structures stained with Masson’s trichrome were foundto be surrounded with a dense collagen. Tubular and acinar structures had PAS po...

Focal epithelial hyperplasia or Heck’s disease is a benign, rare viral disease of the oral cavity and is associated with human papillomavirus 13 and 32 (HPV-13 and HPV-32). Most patients are children but adults may also be at risk. Clinically, the patients have multiple small white or pink papules on the mucosal surface of the lips, buccal mucosa and the tongue. In Iran, this disease seems to b...

Background: Though plausible candidate adhesion systems have been identified, current knowledge of embryo-maternal attachment in human is limited by the inability to conduct well-controlled functional investigations. We have sought a viable medium-throughput model for the identification and functional assessment of molecular markers in the initial epithelial phases of implantation. An ideal mod...

background ovarian cancer is the most common fatal gynecologic malignancy in women. the brca2 gene has a role in regulation of cell cycle during proliferation, differentiation and dna repair. changes in the methylation of brca2 may be an effective mechanism for ovarian cancer. objectives the aim of the present study was to evaluate the association between ovarian cancer and methylation status o...

purpose: to report the clinical, histopathologic, microbiologic and confocal microscopic features of candida keratitis after deep anterior lamellar keratoplasty (dalk). patients and findings: the first patient presented with asymptomatic white to cream-colored interface deposits two months after dalk. confocal scan disclosed clusters of hyper-reflective fine granular deposits in the interface w...

the ultrastructure of the cells, na+, k+-atpase activity and immunolocalization were examined in the barnchial chamber of libellula lydia (drury, 1773) larvae. na+,k+-atpase activity and localization were performed through biochemical techniques and immunofluorescence light microscopy using a mouse monoclonal antibody iggα5, respectively. the branchial chamber possesses six pair gills lamellae ...

Aim: To assess the various morphological types of epithelial origin ovarian tumors. Methods: The study involved cases that were presented to Pathology department between January 2015 December 2020. Epithelial tumors diagnosed as either benign, borderline, or malignant analyzed. inclusion criteria pathological specimens consisting cells are in origin. Clinical records, ultrasounds, and histopath...

Background & Objective: The common epithelial ovarian tumors are classified into serous, mucinous, clear cell, endometrioid, the Brenner, mixed, and undifferentiated types. Cytoskeleton intermediate filament composition of ovarian tissues indicates that the cytokeratin and vimentin are observed in ovarian surface epithelium along with the common ovaria...
