AIMS To investigate whether anomalies of transforming growth factor beta type II receptor (TGF-beta RII) expression occur in the early stages of laryngeal carcinogenesis and to assess their importance in the development of laryngeal squamous cell carcinoma. TGF-beta RII status was examined in laryngeal premalignant lesions coupled with malignant evolution and compared with a control group of si...

primary de novo intraosseous carcinoma is a rare neoplastic lesion which commonly occurs in the jaws. it is an epithelial odontogenic malignancy arising from odontogenic epithelial residues in the bone rather than from a preexisting epithelial lesion. in the present case report, the clinical, radiological and histological features of primary de novo intraosseous carcinoma are discussed and its ...

The aim of this study is to determine whether there is a role of podoplanin and glutathione S-transferases T1 (GST-T1) expression in laryngeal squamous cell carcinoma. The study was completed with 33 patients and gene expression analysis was performed by qRT–PCR. The podoplanin and GST-T1 expression patterns were analyzed to determine their correlation with clinicopathologic parameters of lar...

ocular surface may be involved by different neoplastic lesions ranging from benign to highly malignant. recognition of risk factors, clinical presentations, pathology, and different therapeutic modalities is essential for selecting an appropriate approach. this article deals with the proper approach to ocular surface squamous neoplasia (ossn) including conjunctival/corneal intraepithelial neopl...

background & objectives:  cd10 is a cell surface enzyme with metalloendopeptidase activity, also known as common acute lymphoblastic leukaemia antigen, which mainly serves as a marker for acute lymphoblastic leukemia (all). to date and to the best of our knowledge, only few comparative immunohistochemical studies have assessed cd10 expression in cutaneous epithelial neoplasms. our goal was ...

Background:The incidence rate of head and neck cancer in the world is about 560,000 new cases a year. Larynx cancer is the most common malignancy in head and neck in Iran. The most common head and neck carcinoma is the malignancy of squamous epithelial cells. This study was conducted to determine the survival rate of patients undergoing nonsurgical treatment methods for larynge...

zinc has an important role in skin health and its deficiency reduces immunity. to evaluate levels of zinc in squamous cell carcinoma (scc) and basal cell carcinoma (bcc) of skin, we studied 44 bcc and 38 scc cases together with 33 controls. blood samples were taken and after separation of serum, levels of zinc, albumin and total protein were measured by atomic absorption, albumin kit and reflec...

The aim of this study was to investigate Fragile Histidine Triad Gene (FHIT) expression in laryngeal squamous cell carcinoma. The paraffin embedded tissue blocks of 64 laryngeal squamous cell carcinoma specimens were enrolled in the study. FHIT expression was detected by an immunohistochemical method. Rabbit polyclonal antibody was used for immunohistochemical study. FHIT expression was low in ...

Squamous cell carcinoma of larynx is one the most common malignant neoplasms head and neck. Carcinoma represents 2.2% all cancers in men 0.4% women, with predilection old aged more than 50 years rather women. Smoking main risk factor. Alcohol, nutritional factors virus as Human papillomavirus (HPV) play a role pathogenesis laryngeal carcinoma. Programmed death-ligand (PDL1) new introduced marke...

UNLABELLED Laryngeal squamous cell carcinoma is very often diagnosed at advanced stages. The time interval between the specialist consultation and the start of treatment may contribute to better outcomes. AIM the interval assessment between the first specialist evaluation and the treatment of patients with laryngeal squamous cell carcinoma. STUDY DESIGN longitudinal historical cohort. MAT...
