AIM To evaluate the clinical features, treatment results, and recurrence rates in patients with either intraepithelial or invasive squamous cell carcinoma of the conjunctiva. METHODS Retrospective analysis of 60 cases (22 conjunctival intraepithelial and 38 invasive squamous cell carcinomas) to determine patterns of clinical presentation, aetiological factors, and treatment results. The mean ...

A rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. The patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. The lesion was not painful and caused asymmetry and mild exophthalmos. Microscopic examination revealed that the tumor was composed of two components partly of ...

Background: Squamous cell carcinoma has a wide range of histological differentiation, which indicates the prognosis. Location of the tumor also affects its prognosis. Objective: To determine the relationship between location of the tumor, age and sex of patients and histological grading of it. Patients and Methods: In this retrospective study, 44631 files of the patients who were referred to tw...

Background: Oral squamous cell carcinoma is the sixth most common malignancy in the world today.  ING1b/p33 is a newly-discovered tumor suppressor which enhances p53 activity. Transfer of p33 protein from nucleus to cytoplasmic compartment has been previously reported in leukemias. The objective of this study was to determine the correlation between p33ing1b cytoplasmic transfer and lymph node ...

Aims: To identify roles of human papillomavirus (HPV) infection and solar elastosis as the risk factors for conjunctival squamous cell neoplasia (CSCN). Methods: 30 consecutive pathological specimens, ranging from conjunctival intraepithelial neoplasia, carcinoma in situ, to invasive squamous cell carcinoma were retrieved from tissue archives. 30 controls were disease free conjunctiva from age ...

Conjunctival squamous cell carcinoma (SCC) can develop from carcinoma in situ or severe dysplasia known as conjunctival intraepithelial neoplasia (CIN). Conjunctival intraepithelial neoplasia and SCC are histopathologically well-defined conditions. However, it is difficult to determine the grading of dysplasia by clinical morphologic findings. Recently, proliferating cell nuclear antigen (PCNA)...

objectives : squamous cell carcinoma (scc) is the most common malignant neoplasm of the oral cavity and a public health threat. tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue scc still remains unclear. this study aimed to assess the correlation of these two factors in tongue scc. materia...

this study was conducted to optimize a highly efficient mrna transfection into dendritic cells (dc) derived from esophageal squamous cell carcinoma (escc) patients. applying an electroporation technique, in vitro synthesized green fluorescent protein (gfp) mrna was transfected as an indicator into the dcs derived from a healthy donor. flow cytometry revealed 84.9% transfection efficiency for dc...

background: tumor markers are substances, which quantitatively changes in serum, during the tumor development, one such tumor marker is serum β2-microglobulin (β2-m). the aim of this study was to establish the role of β2-m as a biochemical parameter for diagnosis and prognosis of oral carcinoma by estimation of serum β2-m levels in potentially malignant lesions, conditions, and oral squamous ce...
