Background: Squamous cell carcinoma (SCC) is the most prevalent malignant neoplasm of the oral cavity that exhibits certain histological variations. Verrucous carcinoma (VC) is an uncommon exophytic low-grade well-differentiated variant of SCC. Cellular differentiation and morphology play important roles in cell functions and maintenance of structural integrity .As the cancer is a malignant process in which disorder of the cell growth and behavior occurs, such changes may differ in different tumor types and within different grades of the same tumor. Materials and Methods:Forty two formalin – fixed, paraffin – embedded tissue blocks were included in this study (30 blocks were diagnosed as OSCC and 12 blocks were diagnosed as OV

Background: Colorectal is a worldwide health problem. Tumors stimulate the ground of host blood vessels, a process called angiogenesis, which is essential for supplying nutrients of the tumor, also stimulate the lymphatic vessels for metasatasis.

Background: Colorectal carcinoma is the most frequent type of malignancy in terms of incidence,it is the third most common cancer world wide in both sexes . bcl_2 expression has been described as been a better prognostic factor in colorectal carcinoma.
Objcetives: To determine the frequency and the pattern of Bcl-2 expression in colorectal carcinoma by immunohistochemical technique and to correlate this expression with different clinicopathological parameters.
Material and method: Thirty cases of colorectal carcinoma were studied, these cases were diagnosed in private laboratories in Baghdad / Iraq from January 2015 to Juan 2015. Clinicopathological parameter such as age, gender , pathological diagnosi

B-Cell lymphoma 3 is a putative proto-oncogene that involved in central oncogenic pathways that regulate cell death, apoptosis and metastatic of tumor cells so it could be important as a target to validation as a diagnostic or prognostic marker in these tumors. This study revealed positive expression of Bcl3 in (76.6%) of 47 cases infiltrating ductal carcinoma and (61.7%) of positive were strong positive. These results showed no significant association of immunohistochemical expression of Bcl3 with clinicopathological features as well no relation with immunohistochemical expressions of estrogen rreceptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2/neu).

Background:- Colorectal carcinoma is the most common cancer after the breast cancer in female and bronchus cancer in male. P53 is a tumor suppressor gene, approximately half of colorectal cancers present mutation in p53 gene.
Objectives:- To determine the frequency and the pattern of p53expression in colorectal carcinoma by immunohistochemical technique and to correlate this expression with different clinicopathological parameters.
Materials and methods:-Thirty cases of colorectal carcinoma were included in this study, these cases were diagnosed in private pathology laboratories in Baghdad / Iraq from January 2015 to Jaune 2015. Clinicopathological parameters such as age , gender , pathological diagnosis , including the tumor site

BACKGROUND: Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma that represents a set of characteristic of nuclear features in which the diagnosis is depend. AIM: The study aimed to review different variants of PTC which has different malignant potential in correlation with many prognostic and clinical factors in Iraq. PATIENTS AND METHODS: Paraffin blocks of 227 cases of PTC were selected, subtyped, and grouped according to the malignant potential. The prognostic and clinical factors were studied. RESULTS: The mean age was (39.29 ± 12.17) years, with female predominance (86.3%), where (55.5%) of them below 40 years, conventional variant was most common (40.1%), followed by papillary microcarcinoma

Background: Lung cancer is the leading cause of cancer deaths and its incidence is rising. The determination of histopathology and stage of primary lung carcinoma is crucial to develop appropriate treatment approach that affects morbidity and mortality. Fiber optic bronchoscope techniques for early detection of lung cancer are a promising tool as they might allow visualizing changes of early lung cancer and also permitting sampling for histological confirmation.
Objective: This study was intended to compare the fiber optic bronchoscopy findings and their anatomical locations with the histopathology types in patients with lung cancer.
Patient and Methods: A cross section study was conducted during the period

Background: Alteration in the expression of p53 tumor-suppressor protein is an event that occurs frequently in human cancer, but the practical implications of this phenomenon are yet to be fully exploited.
Objectives: to determine the value of p53 expression as a marker of tumor aggressiveness and the relationship between p53 over expression and clinico-pathologic variables in gastric adenocarcinoma.
Material & Methods: The expression of p53 was studied immunohisto-chemically in 10 cases with gastric dysplasia and 85 cases with gastric adenocarcinomas using formalin fixed, paraffin-embedded tissue samples. D07 a monoclonal antibody to p53 protein was used for the immunehistochemical analysis. The c

Introduction: With the advent of era of targeted cancer therapy, the serious side effects of chemoradiotherapy have been minimised. Considering the success story of anti-HER2/neu drugs in breast cancer oncology, the present study was conducted. The study evaluates the immunohistochemical expression of HER2/neu in endometrioid cancer among Iraqi patients. Aim: To assess the immunohistochemical expression of HER2/neu in endometrioid carcinoma of uterus and to find the relationship of this expression with FIGO stage and grade and with patient age. Materials and Methods: In this cross sectional study, formalin-fixed, paraffin-embedded tissue blocks of 62 hysterectomy specimens that were diagnosed as endometrioid carcinoma in the teaching labora

Background: P53 is an important tumor marker in many malignancies, the P53 gene is a tumor suppressor gene that plays a key role in the regulation of the cell cycle.
