Background and objective: Involvement of lymph nodes is an important prognostic factor in most cancers, including colorectal cancer in which lymph node status is the strongest pathologic predictor of patient outcome. This study aimed to find any relationship between lymph node metastasis and associated clinicopathologic variables in colorectal carcinoma.Methods: In this retrospective study, 136 cases of colorectal cancer were reviewed from Rizgary Teaching Hospital and some private labs in Erbil, Kurdistan region, Iraq during the period between August 2010 and December 2015. All cases were surgically treated with total colectomy or hemi colectomy.Results: A total of 136 cases of colorectal cancer were included in this study; 53% presented with one or more lymph node metastasis, 47% were between 40 and 60 years of age and 68% were male. There was no statistically significant relationship between lymph node status and any of the studied clinicopathologic variables. Conclusion: In colorectal adenocarcinoma, there was no statistically significant correlation between lymph node involvement and any of the studied clinicopathologic variables including tumor size, anatomic location, differentiation and histologic type, depth of invasion or patient gender and age.

Background and objective: Fine needle aspiration cytology with cell block preparation is widely used for preoperative confirmation of solitary lung mass and classification of the histologic types. This study aimed to highlight the importance of cell-block preparation in the diagnosis of primary malignant lung lesion by comparing cytomorphological preservation on paired cell block and conventional fine needle aspiration samples. Methods: During January 2012 to October 2015, a total of 100 cases with solitary lung mass were included, either visited Rizgary Teaching Hospital or Walfare private hospital. All the patients had undergone fine needle aspiration and cell block preparation under a CT-guide.Results: The samples were evaluated by the fine needle aspirations and cell blocks preparations from primary lung lesion under a CT-guide. 74% were male, and the majority of them were in the sixth and seventh decade. Squamous cell carcinoma was the most common histologic type consisting 42% of the studied cases, followed by adenocarconima (31%), small cell carcinoma (19%) and the remaining 8% were large cell carcinomas. In the assessment of agreement of cellularity between the two methods of sample preparation, cell block served better than fine needle aspiration (P = 0.715). However, this difference was statistically non-significant. A significant relation was found for morphology which was preserved in fine needle aspiration samples better than that in cell block samples (P <0.05). In contrast, all cell block samples displayed a statistically highly significant architectural preservation compared to fine needle aspiration samples (P <0.001). The sensitivity and specificity of the present study were 98.46%, 99.2% respectively. Conclusion: Direct fine needle aspiration smears and cell blocks complement each other, and our results indicate that both are needed in the diagnostic work-up of patients with a primary malignant lung mass.

Background and objective: Trophoblastic diseases constitute a spectrum of tumors and tumor- like conditions characterized by proliferation of pregnancy associated trophoblastic tissue of progressive malignant potential. This study aimed to assess the value of p53 protein immunoexpression in the diagnosis of hydatidiform molar pregnancy and the differential diagnosis of its subtypes (complete and partial) from abortions.Methods: A cross-sectional study of tissue sections from 68 formalin-fixed, paraffin- embedded specimens of products of conception, including 1st trimester abortion (n=15), partial hydatidiform mole PHM (n=24), complete hydatidiform CHM (n=24) and full term placenta (n=5), all were examined at the Histopathology Department of Maternity Teaching Hospital in Erbil, Iraq during the period of Jan.2013-Jun.2013. Immunohistochemistry was performed using p53 antibody and the standard streptavidin-biotin immunoperoxidase method. The labeling index (number of positive nuclei/total number of nuclei) for villous cytotrophoblasts, syncytiotrophoblasts and stromal cells were evaluated separately. Statistical analysis was carried out by one way ANOVA and Fisher's exact tests, statistical significance was determined at P ≤0.05.Results: All villous trophoblastic lesions showed higher p53 immunoexpression in all villous components especially cytotrophoblasts, being the highest in complete hydatidiform mole (>50%) and partial hydatidiform mole (>20%). A statistically significant difference was found in immunoexpressins of p53 that was useful in separating abortion from complete hydatidiformmole, P <0.001, and partial hydatidiform mole, P <0.0002. It was also useful in separating between the complete hydatidiform mole and partial hydatidiform mole (P <0.001).Conclusion: p53 immunoexpression was valuable in differentiation between molar and non molar pregnancies and between subtypes of molar pregnancies.
