Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...

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: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

Background & Aims: Leukoplakia is the most common premalignant or potentially malignant lesion of the oral mucosa and its potentiality for malignant transformation is unpredictable. The aim of the present study was to evaluate p53 expression in normal oral epithelium, leukoplakia and oral squamous cell carcinoma. Methods: The standard Biotin streptavaidin peroxidase immunohistochemical staining...

BACKGROUND Cervical cancer is the second most common cancer in women worldwide. Recent studies show that human papillomavirus (HPV) DNA is present in all cervical carcinomas and in some cervicitis cases, with some geographical variation in viral subtypes. Therefore determination of the presence of HPV in the general population of each region can help reveal the role of these viruses in tumors. ...

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 ...

snus (nass) is a form of snuff used in a similar manner to american dipping tobacco, but it does not typically result in a need for spitting. possible hazards associated with this material include malignant and premalignant lesions in the oral cavity and gastrointestinal tract. the use of smokeless tobacco has increased in the middle east in recent decades, particularly among teenagers and youn...
