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 ...

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...

Background: Lung cancer ranks among the most common and most lethal malignancies worldwide. Once vascular or lymphatic invasions occur, metastatic dissemination to distant sites is common. Bone, liver, adrenals, and brain are the most frequent sites of the distant disease. In this study we present a case of squamous cell carcinoma of lung with metastasis of the left knee bursa.Case presentation...

background: the most frequently mutated tumor suppressor gene found in human cancer is p53. in a normal situation, p53 is activated upon the induction of dna damage to either arrest the cell cycle or to induce apoptosis. however, when mutated, p53 is no longer able to properly accomplish these functions. the aim of this study was to investigate the expression of p53 gene in cases of skin cancer...

background and aims. helicobacter pylori is a microaerophilic gram-negative spiral organism. it is recognized as the etiologic factor for peptic ulcers, gastric adenocarcinoma and gastric lymphoma. recently, it has been isolated from dental plaque and the dorsum of the tongue. this study was designed to assess the association between h. pylori and oral lesions such as ulcerative/inflammatory le...
